Questions related to Paint
Hi all,
I'm looking to mass mark Solenopsis xyloni ants during an experiment. For this experiment, I'm allowing the whole colony to feed on three feeders, and I want to mass mark all the ants that are visiting the feeder and returning to the nest with a unique color corresponding to each of the three feeders. I was reading about various mass marking techniques and it seems two main methods exist so far: Powder paint application (dusting it with a brush) and spray painting using small atomizers or airbrush. But I cannot find a good powder paint that is non-toxic to ants. Also, I do not want to permanently mark the ants. BioQuip had a couple of powder paints used by several researchers, but unfortunately, the company is no longer operational. Any suggestions for good powder paints or paints for atomizers (in the U.S. market)? Also, do any suggestions for specific atomizers or airbrushes that worked for you?
Let me know if you need more information to answer this question.
Thanks in advance!
Hello. I conducted batch leaching tests with samples of construction and demolition waste with adhered paints to assess the influence of the paint on the release of contaminants in the leachate. I observed that in all samples with water-based enamel paints, the pH of the leachate was significantly lower compared to the samples painted with acrylic paints. What could explain this decrease in pH?
We would like to mark nocturnal animals with something that we can see with an infrared camera, and ideally use in a way to be able to differentiate between animals. Does anyone have any experience or suggestions of something we can use?
Greetings Everyone,
I need some suppliers which can provide Protective Microwave Transparent Paint for Antenna PCB. Kindly let me know the details of the suppliers.
I've requested the full text for this journal but haven't anything back. So I was just wondering if anyone know where I can download it from as it will really useful for my dissertation
There are many white coatings or solar coatings available commercially, but is there a radiative cooling paint available commercially?
does anyone know why there is an air gap at the end of the pipette tip every now and then after aspirating? it seems to occur more often when pipetting larger volumes on a P1000 but can also occur when say using a multichannel pipette on lower volumetric pipettes. pardon the poor paint image to depict what im trying to get across
is this a operator error or is it natural to occur? if an operator error, are there any tips to avoid this?
I am working with acrylic latex using styrene and butyl acrylate with 50% solid content. How can I reduce the viscosity of the latex?
The other question in this subject: how can I adjust the pH to 9, because I used 40% NaOH for 200g latex (about 10g) , NH3, NH3/NH4Cl buffer but I didn't achieve the desired adjustment.
I was reading a few articals for my research on TiO2 used in paint formulation, and I found only few extenders like Calcined kaolin, Hollow spheres, Barium sulphate that could reduce by little the amount of TiO2.
Isn't there any other substitute for TiO2 pigment that have a less environmental impact?
Hi !
I come to ask for help. Indeed I try to isolate an object in an image with XnView and paint but the object to isolate appears blurry.
So please help me either with other tools or methods.
THANK YOU
I need to make low cost reflectance calibration samples. I plan to apply special paints on a plywood board.
For high reflectance, BaSO4 paint works well, but I can't find low (10%) reflectance composition.
Does anyone know a supplier or a recipe to buy/make such a paint?
Thanks!
Dear Colleagues,
Please give me a hint how to expand the process window of laser paint etching on painted plastic parts?
The task is to reduce the sensitivity of the laser process to variations in paint thickness.
Which of the laser etching parameters can be changed to expand the process window between burning the material and not etching the paint?
I have: laser beam speed, frequency and line spacing.
Thank You.

Can anyone suggest the literature sources/LCA data on Paint (water based and solvent based) manufacturing and end of life treatments such as reusing, recycling (remanufacturing) and incineration?
I try to add white background on the big image by using Paint 3D. Originally, the size of big image is 9825 x 9908 pixels. But after adding the background, the size is automatically change to 6198 x 5885. May I ask why auto-resize will occur and how is the final size be calculated in the Paint 3D canvas ?
I have a very thin sample of BNNT that is heated up and I need to measure it's temperature using a long wavelength IR camera. This BNNT is of unknown emissivity and I currently unable to measure it using a spectrometer. My thinking is that I can attach or apply a layer of a material of known optical properties to the bottom of the paper so I can measure it's temperature instead. Since I will be applying a think layer, I am assuming the temperature would be the same. I am expecting the temperature of the sample to be between 300 and 500 degrees Celsius.
Now my question is what can I use? I found one Thermographic paint that I can use but the distributor is in Europe and I am in Canada, so it would take some time to obtain the paint. I am looking for other alternatives before making a decision.
I want to understand the stability of pigment particles over time. I have an old sample (unchanged for 2 years), a new one (manufacturing 2 months) and mixed (old sample was mixed). I want to understand how much I need to change (mix) the paint so that it is like new again. Is it possible to use a method to measure ZP (DLS) to understand how paint can degrade? How can particles agglomerate?
Hello Colleagues
For our project, we are looking for a layer that blocks visible light and allows infrared radiation to pass through.
We would like to use such a material in the form of a film (sticker) or paint.

I am looking for suggestions for a chemical resistant paint/coating which I can use to cover the sides of the steel plate except for one face for corrosion testing. If anyone has any suggestions please let me know. Thank you
I would create my plates (a group of histologic figures) in MS paint, then save in irfanview, where I resize and adjust to desired dpi. I couldn't group figures, label, adjust contrast, etc in irfanview. I thought there should be a software that does it all.
Dear Colleagues,
I want to use RS Pro Silver Paint ( 186-3600) on a pellet for making electrical contact.
Does this paint work at cryogenic temperature?
I can't find the service temperature .
Please help with discussion.

We are experiencing some corrosion/peeling of the white paint inside the Akta F9-C fraction collector. We suspect that this is due to overflow while washing the fraction arm under high flow rate after runs with high salt (6M urea). We have since fixed the overflow issue, but are curious if anyone else has experienced this paint corrosion/peeling before and if so, did it cause any further problems? For example, did the metal under the paint begin to corrode? Was there anything you did to re-seal the corroded area?
Thank you in advance for any comments/advice!
Best,
Kira
Most preferable method should work with thermoplastic paint, however other suggestions would be welcome along with the relevant Information.

Solar Paint technology:- Solar paint, also known as photovoltaic paint, is exactly what it sounds like! It’s a paint that you can apply to any surface that will capture energy from the sun and transform it into electricity. The paint would essentially be your average paint, but with billions of pieces of light-sensitive material suspended in it, material that would transform the typical paint into superpowered energy-capturing paint.
Present I am working on different technologies included in itself and how to develop the infancy to developed stages and what are the implementations and challenges are facing in the future.
If a iron metal rod is kept outside in ambient air (temp condition extreme low and high -10 to 50 degree) and another iron with some paint (normal oil paints)/ zinc coat kept . What will be the effect of coating on heat gain of iron.? Will it attain more temp than which no coated iron rod.?
Also what will be effect on the thermal expansion of metal due to it.?
I came across a very nice diagram in the following article, Fig. 2A
and since I've been wondering, how does one produce such a diagra in a (semi) automated way? Of course one could use Microsoft Paint with a lot of patience - but if any of you know an elegant solution, I'm very keen to know.
Hello and Good Day to everyone,
I am currently planning doing some research of adhesion effect for the hot dip galvanizing on the painted steel. Most of the galvanizer having big problems when doing cleaning prior galvanizing process. Thinking some of primer paint that being used in the industrial to be tested for the hot dip galvanized process like zinc rich primer.
Thank you
Hello,
I am trying to make artificial muscles out of the nylon fishing line and to actuate the muscles I plan on using joule heating, but I have read some research papers which say that we can apply conductive silver paint on the nylon and then pass the electricity through it, but wouldn't it take a lot of energy to to heat the silver since it has a very low resistance, I also want to know if its feasible to use Nichrome wires instead of silver paint for joule heating.
Thanks

Hello, fellow education research and action leaders,
As part of an education-focused project, Green Teach for Opportunity, a small team and I are researching the opportunities and pain points educators perceive related to teaching sustainability skills* across and among disciplines. I read and appreciate your work on this topic, following many of you, and also offer several books, articles, and informal research papers here on Research Gate as well.
The question above is an attempt to better understand the level of interest, indifference, and relevance faculty and teachers (secondary and post-secondary) are feeling about sustainability skills education in general, and also related to career preparation specifically. If you would kindly answer this question, it would be helpful to know the relevance, if any, you see on a scale of 1-10 (1-least important/relevant and 10 most important/relevant).
"Relevant for what," you may ask? The intent here is primarily to gauge the relevance or importance you see relative to the learning objectives for your particular course or curriculum (specifically, for classes you teach, or courses of study you directly support, i.e., in a curriculum development or similar role.)
It would also be helpful to know your title, discipline, or major you instruct or support, and also your state (if in the US) or country. If you wish to provide your name and email to stay posted on findings and updates from the Green Tech for Opportunity project, that is of course not necessary, but would be appreciated.
*The term "Sustainability" in this question is meant to encompass diverse concepts and approaches related to sustainable well-being for all, including environmental, regenerative, sustainable development, conservation, and green education. Although these terms represent some variation in vision and approach, there is usually a good deal of overlap in intent. Your opinions on this matter are also welcome.

The four samples shown are paint samples which were dried and ashed using a drying oven, followed by a muffle furnace. A small amount of the ash was used on gold stubs for SEM imaging. However, I am struggling to interpret the results as all the samples look very similar. Much of the literature regarding SEM and paint samples involves the detection of different layers, however the sample was ashed and therefore this is not relevant. How would these SEM images allow me to distinguish between the paint samples?
We are using an aluminum/steel plate as a protection shield facing concentrated solar irradiation of 1000 Suns. The shield is watercooled to keep the temperature <400C, however We want to minimize the incomming radiation using a highly relective (> 90%) paint (and in future maybe a coating).
Required a spray or paint which can resist the heat flow between two steel block in physical contact. Working temperature is 250 degree celsius.
at least some techniques on how some extracts can be obtained from plants.
Researchers working on photoelectrochemical hydrogen production, use EIS results to describe mechanism of charge transport inside and at the surface of electrode. Flat band calculations are also done by EIS. Can we use results of IS because in IS pellet is usually coated with silver paint and that silver paint act as electrode. So could we use the mechanism of charge transfer estimated from circuit fitting of IS results to explain the PEC usefulness of a material?
As we know one of the main ingredients in paint industry as a pigment is Titanium dioxide. However it costs too much. Considering these two facts in our mind, I want to know, how it is possible to diminish the usage of TiO2 in this industry?
I'm submitting manuscript to a journal that requires 1200 dpi in my images. I have changed the dpi from 96 but when I upload the image with 1200 dpi, the image looks super blurry when I review my manuscript. If I open the image in word/paint/other the resolution is great but in the submission it looks blurry. It is the right dpi but it is impossible to see the figures. What should I do? I don't want this to be a possible reason for the journal to not accept my manuscript.
I am looking at doing an honours research project on Dolomedes tenebrosus. It would involve marking them with paint in the field, but there are no resources that I can find explaining the proper handling and no one in my area has done research on them before. Any help would be appreciated, thank you!
The aim is to draw an energy flow in a certain industrial process as a "big arrow", whee "small arrows" will show the losses taken by different issues. These pictures may be widely seen in different papers and books, but what is the best way to draw them, other that "paint"?
Is there any report on surface oxidation of silver nanoparticles that are embedded in paints and coatings used against microbial fouling on buildings, monuments, etc? Also, what is the likelihood of surface oxidation in such a scenario where there is an existing chemical bond/interaction between paint matrices and nanoparticles? How far does the phenomenon of oxidation affect the performance of these coatings, if at all? Are there any existing strategies and technologies that are applied to overcome such a challenge?
The adobe illustrator has a steep learning curve, the MS paint is not that robust, pictures pixelate when resized and not enough features. Please feel free to suggest.
I am looking for paint or in an extreme case a coating material on inAtmosphere flying object to reduce the heat dissipation caused by aerodynamic heating for a relatively longer period, considering the speed range of upper hypersonic range.
I have fabricated graphene Hall device with contact pads of Cr/Au of size 200x200 um^2 with separation of ~300 um between two pads .I am having some issues with wire bonding. So, I want to know which is the best conducting adhesive for making wire contact between contact pads of the device and pads of the chip carrier, compatible in a wide range of temperature (~ 4K-300K) as an alternative to the wire bonding?
Thanks in advance.
You have a solution for removing paints from containers such as disposable polypropylene and polystyrene cups for recyclable?
Do anyone knows what kind of materials could be used to paint a supercapacitor electrode as shown in the picture (the coated black shining materials)? Any help is appreciated. Thanks!
Is there a model or other technique to estimate the useful lifespan of zinc-rich paint based on EIS data? I will not be able to undertake long-term testing of actual corrosion rates for comparison.
If a comparative Time To Failure (TTF) in a salt fog environment can be obtained following Kendig's method can this be extrapolated to a TTF in atmospheric conditions? Feliu has done long-term assessment of ZRPs but does not correlate these results to short-term or rapid assessment techniques.
I am aware REAP may not be the ideal method. My colleagues found no disbondment at the scribed edge after 24h immersion and so defaulted to an estimated value for the needed dx/dt term. If a longer-term method is necessary, what is the minimum time period for a reliable estimate of actual period of protection? And what other analysis is advised in either case?
I am looking at a 96wt% Zn (dry film) paint applied over weathered hot-dip galvanising.
i am working in alloy wheel manufacturing company where wheels get paint and goes to the oven for curing and drying. since few days some wheels get matte finishing which is not required as we are using the gloss paint.
so, what would be the reason that glossy paint becomes matte sometimes?
For a senior thesis I am designing an open structure (think kiosk, pop-up shop or other semi-permeable shelter) which will primarily feature a solid roof and basic support geometry. The roof will be pitched and the model will need to illustrate attachment of photovoltaic panels and rainwater re-direction. The structure is designed to securely contain 3-4 machines about the size of 10 gallon paint buckets; the enclosure of which will require some basic moving parts i.e. hinges.
Material possibilities: Extruded and/or corrugated sheet steel, aluminum, wood, concrete, mud/thatch.
While I have some experience with SolidWorks, I have mostly designed small products as opposed to structures and am wondering if I should try modeling in Rhino or another program instead. As a student I should be able to access any program on a trial basis at the very least. If anyone with experience would lend some insight that would be greatly appreciated!

Good day, dear colleagues
I have some question for You
I'm working on the powder painting of details with difficult geometry.
The tribostatic method has a good result about this
I try to use electrostatic method to deside this problem. But the Faraday effect is a big problem.
Can anyone give some advice how I can paint the difficult detail (picture in the letter)?
Thank You for Your time

I am currently researching the components and methods of ochre paint preparation used in rock art from the holocene in North America. While ochre paint use in prehistory is a heavily researched topic, there seems to be a lack of information on the preparation and ingredients used (binders, liquid, any additives). I wonder if there are any documented oral accounts of pigment recipes (I have found some documenting the use of seal fat and linseed oil for instance), or if there are any compendiums of components found in prehistoric ochre paint.
Thank you
I am from India, where we have dust every where. No matter how frequent we clean, dust keeps on settling like you see in interstellar movie. Its tiring repetitive process of little use to blow/suck air and still over time, sticky dust are on every bump on walls, creeks on windows, etc.
Are there any creative effective ways of handling dust or preventing them in first place? I thought of crazy budget solutions like
1. 24/7 Misty minute water spray from pillars around the house, so as to bring down dust particles at least in my house environment
2. Super hydrophobic paint (can they be anti dust as well?) or super slippery painting or cementing?
I do not know if they work, and if I could afford, so I hit a wall here, looking for help.
Old wall paints are generally removed using scrappers/ sandpapers etc. The dust particles are dangerous to health. The problem is need to solve by suitable cost effective mechanism either by using certain chemical to remove paint depending upon type of paint or by certain technique. The quantity of waste materials from removal of paint is need to be disposed off properly or reused for other purposes.
I am working with a waterbased paint with thixotropic behaviour to some extent. I want to know if someone is aware of a way to correlate between the value of viscosity obtained using a Haake Viscotester 550 and a TA rheometer. Thanks.
Quantum Yield(QY) decreases significantly when I coat my PbS QDs (It decreases from 50% (in solution form) to a maximum of 18%(in the thin-film). A possible explanation is that QDs get closer to each other in films. Is there any way to improve QY of films? I've tried a number of solutions including embedding in polymers, mixing with paint, varnish, etc, but haven't succeeded yet.
Dear all,
Is there a database that provides the vulnerability/degradability information of different matrix toward weathering (i.e. the matrix of product used for outdoor application: paint, range of polymer, cement, glass). The data could be in the mass loss by surface by the time of weathering or by energy, if you not possible to get quantitative information, qualitative data could work. Quantitative information and mechanisms detail could be terrific :).
Thanks in advance for any of your responses and your time.
Best regards,

Greetings,
Currently, I am trying to develop a new paint formulation. I already have in mind on what type of pigment and additive that I want to use. The problem is, I do not have a good idea on the type of binder to select. I have seen quite a lot of paint been commercialized, but I am worried that if the paint I buy on market will already have their own pigment and additive. If yes, then the uncertainty of what type of pigment they used will not give me a clear understanding on its formulation.
So, can anyone give me specific suggestion on the type of paint binder to buy? Probably the key words to find them will also be useful.
Hello.
I am trying to formulate a waterborne coating for marine purpose. The problem is, i could not find a suitable binder such as resin/acrylic paint for this project. Some of commercialize binder already pigmented. Where can i find pure acrylic/resin that suitable for waterborne coating.?
Thank you
I’m supposed to synthesize alkyd resin while the reaction setup is made anaerobic by nitrogen gas. However, the procedures I have read use sparging rate (i.e. 0.05 cubic feet/sec for alcoholysis and 0.1 cubic feet/sec for polymerization) instead of pressure. Do I need to get a flowmeter or is there a way to do the procedure without?
Why snow an paint are called black bodies though they look white to us..
In the steel construction sector, the same types of paint are used from project to project. Each type of paint is designed to meet specific needs to satisfy the particular requirements of each individual project. Paint finishes can be used for esthetic purposes, permanent or temporary protection, and color identification. First types of paint generally utilized in the industry is the standard grey primers are generally provided as alkyd paints, the grey primer applied to joists either by dipping or with a paint gun is normally an alkyd paint ....
How can we carry an evaluation study for such materials that must be used in sever conditions...?
what is the main difference between paint and polymer coating in formulation. I mean the ingredients like additives etc. Also is there any difference between them from curing viewpoint?
Hello, I'm a recent BSc graduate starting a Masters in the coming weeks. My interests lie in the areas of woodland fragmentation and, more specifically, carrion and Silphid ecology. My undergrad dissertation looked at species abundance and richness in different woodland sizes using baited non-lethal pitfall traps. My question, if it is appropriate to ask, relates the choice of topic/design for my Masters thesis. Of course, I haven't started with the university yet, but I thought it would be good to get some preliminary input.
I collected a good amount of sources (around 40-50) on Silphid ecology and I have a decent grounding, at least at BSc level, of the issues that Silphids face in relation to their changing environments. I just wonder how I might elevate my studies further and employ 'Masters level' techniques.
My study was limited in that it used only 4 woodlands (2x ' large', 2x 'small') and did not take into account any environmental factors. It was essentially a comparison between the Silphid composition of the large and small fragmented woodlands set apart by 2 miles (out of olfactory detection rage). Recurring individuals were noted by non-toxic marking paint applications each sampling session.
I suppose if I were to ask a more concrete question: what would you say would be a good and achievable Silphid research paper/experimental design? I have a few ideas on how to elaborate on my original work, for example by including more advanced woodland metrics, increasing the sample size of woodlands, accounting for canopy density (something which may impede Silphids), etc. but I would like to tackle a real and genuine problem. We know already that Silphids are affected by fragmentation. I like the idea of using real carcasses to assess interment rate as I'd be able to show more clearly the effect on the ecosystem service, but I don't think that would add much to the literature as we know carcasses are less prevalent where mesopredators are abundant, e.g. edge. I wonder if I could use micro satellites? That may beyond my skill set at the moment though.
Put simply, is anyone able to provide a definite question they would like to be answered about Silphids? It would be very helpful. A lot of the papers I read recently were quite above my level and involved genetic analysis, so it's hard to gauge which sort of research question may be appropriate for me.
Hi I am preparing enamel paint from alkyd of medium oil length. I found that the first coat of paint is getting tack free in 7-8 hours whereas the second coat is tack free in 5-6 hours. Can anyone explain this phenomenon of fast drying of second coat over the first one.
I am interested in learning on the topic of VOCs emission by marine coating. I have read some articles which claim that VOCs emission does not only emitted during the initial stage of application, but can continue to do so for a long period of time. As such, I have been thinking, since coating applied on marine vessel is exposed to the aggressive solution of seawater, wont this accelerate the oxidation of the coating and faster released of VOCs?
I try to find any articles in relate to the topic and idea, but sadly I cannot find much. Any help would be much appreciated. Thank you in advance !
Is it possible to add metallic power (Fe, Co) to a type of epoxy, to create a "paint" that is susceptible to inductive heating?
I have attempted to add Iron power to a carbon based high temperature epoxy and inductively heat it, however I could not reach temperatures beyond 100C. Perhaps if the epoxy was electrically conductive, this method might work?
I have not found any product online that is designed for this.
Hi everyone! What is the best way of marking a money spider with a body length of 1.6 - 2 mm. Using a non-toxic and odourless acrylic paint seems the best option so far, but how to apply it safely without harming a spider? Does anyone have experience? Any suggestions are appreciated.
I have a cylinder which is 3D printed. Due to the material being porous, when submerged it absorbs water and eventually softens and misshapes over time. This cylinder has a complex surface topology on. I need to find a way to coat a water-resistant material on it but in a way that assures thickness uniformity everywhere on the surface. That is the reason we cannot paint it with a spray paint or a brush. We need to make sure we do not mess up the surface topology.
I work with insects and the anti-climbing paint seems to get everywhere. How can I remove it from my clothes? It seems very resistant to general washing and water, any safe solvents I could use to remove it?
