Thank you for your kind comment. Much appreciated.

We use Formula Software

In ISO 2812-3, you have 25 or 36 mm filter paper discs specified in section 4.4, with the note 1 that discs with a thickness of 1.0 to 1.25 mm are best. This is the absorbent material you see in the video. If you would like to purchase such filters ready for such a test, please contact us because we offer them.

Hello there,

@@SpektrochemResearchLaboratory I'm Tanzeel from Pakistan with small business of paint manufacturing

@@PAINT.PRODUCTION Kind regards from sunny Poland

Thank you for your comment. The video is not intended to allow you to understand how to perform the test, but to show that we perform it in our lab. To understand the procedure, you must familiarize yourself with the ASTM D2697 test method and gain experience in performing this test in practice. If you need consultation or training, we offer it.

Thank you for your kind comment.

It all depends on whether you accept cohesive failure at this value. In general, yes, if the result is 6 MPa / 870 psi and you have a minimum adhesion of 5 MPa / 725 psi in the specification, then the requirement is met.

Adding chalk/calcium carboinate or talc filler will cause flattening, but the question is whether this is the only effect you care about. Please keep in mind that increasing the share of fillers in the formulation disturbs the PVC (Pigment Volume Concentration) and the ratio (pigments + fillers): binder, which affects not only the gloss, but also scrubbability, porosity and many other parameters such as durability. Following the addition of fillers for flattening purposes, you must also consider modifying the dosage of the dispersing agent. Other ways to reduce the gloss are to use additives, such as matting waxes, depending on whether you want to achieve flattening in the gloss at 60° or sheen at 85° range. If you would like to consult us for advice on formulations and raw materials, please contact us by email.

@@SpektrochemResearchLaboratory thank you for your detailed reply, I appreciate it 🙏

I'm not sure what you mean? Can you elaborate?

Definitely, it will be the correct method to evaluate

@@SpektrochemResearchLaboratory can you help me to discover how dispers correctly pigments in oil?

@@lacucinachimica Of course, please contact our expert Dr Artur Palasz www.linkedin.com/in/arturpalasz/ or send us an e-mail customerservice@spektrochem.pl to transfer your correspondence

We do not sell testing equipment, but we can offer you technical support and consultations to select the right grindometer and help interpret the results and implement the ASTM standard for performing the fineness of grind test.

The whiter surface is the tin side, just like in the video. This is about the surface that is in contact with the lamp (from the bottom of the glass panel). As ASTM D3891 specifies: the air side will appear clear, and the tin side will appear frosted. There is no mistake in the video. You may have interpreted that it was the top side of glass panel, but the video clearly shows that the tin side and air side are from the side of the UV lamp.

​@@SpektrochemResearchLaboratory The labels are on the incorrect surface for which they identify. It's like you didn't read my comment. The label for "Tin side" is adhered to the "air side" of the glass.

Depending on what tests you want to perform later after exposure. If only fading/chalking/color is assessed, aluminum Q-Panels are sufficient. If you want to test the entire coating system with a primer or evaluate, for example, the adhesion of architectural paints to the substrate, concrete panels will be a better option.

There are many liquid thickeners for latex paints. Starting from all PU thickeners (HEUR), through acrylic thickeners (HASE, ASE), to some that must be added in the form of suspensions and pre-gels prepared from powders.

The ASTM D4400 standard indicates the use of charts.

Please contact us directly by e-mail. We can consult your case.

All details you can find in ISO 3251

Thanks!

Thank you!

This is nothing special related to the test. An ordinary anti-slip pad for a cell phone, so that the grindometer does not slide on the table, which is quite slippery ;)

Thank you. Much appreciated.

Unfortunately I have no idea where you can get it in Turkey. The material we use is specified by ASTM and comes from the US.

Please see ASTM D344 standard. There is full procedure how to calculate results.

This music is perfect for everyone to remember this video.

whats the song name?

This is some track from the YT library, but I can't find what it was. Search the library in YT studio in the electronic music category.

My pleasure.

What benefits are you thinking about? In inks… does that mean?

Thanks

The webinar was paid and held live.

Overall, it's hard to compare for many reasons, but opacity was definitely worse.

You need to establish a balance between PVC and fillers responsible for sheen (silica, kaolin) if you are talking about sheen as gloss @85°, because remember that in the definition gloss is @60° and sheen is @85°.

If you need consultation in this regard, please send us an e-mail.

Thank you very much. I really appreciate your kind comment.

This is our cowles dissolver from the Polish manufacturer of production equipment, TEST company

Cheap and reliable is a fine line and balancing on the edge of risk. Would you believe the results of tests done cheaply on unreputable equipment? Probably not. That's why we only use traceable, world-class equipment from proven suppliers

@@SpektrochemResearchLaboratory sounds unaffordable. But no, I just need anything that gets me 1-2% margin of error on volume solids. I don't need top of the line machinery that's .0000000001% margin of error you get me?

@@zsurvivalist7996 The ASTM D2697 standard indicates all the limits of precision, repeatability, reproducibility, etc. An analytical balance does not have to be very expensive, but it must be calibrated and checked regularly, your laboratory conditions must be monitored and meet temperature and humidity requirements if you want to maintain the reliability of your measurements. In addition, proficiency in performing tests, which means that if you want to perform such tests, you must ensure appropriate standards. The precision of the ASTM D2697 method is just that, providing 1-2% volume solids. I don't know why you think it's 0.0000001% here?

@@SpektrochemResearchLaboratory well that was an exageration and sort of a joke. I'm just some idiot in over my head trying to learn things so i can test our products more precisely since I don't believe I've been taught correctly how to do things where I'm at.

@@zsurvivalist7996 I don't think you're an idiot... I think you deserve recognition because you're trying to find how to do something right and you want to learn... Start with a 0.001 analytical scale with ASTM D2697 volumetric weighing attachment and compare your results to some known value of volume solids

PVC is not a binder, but a Pigment Volume Concentration. Perhaps you meant polyvinyl acetate copolymers (with ethylene, VeoVa, versatic esters, acrylic monomers, etc.)... It is impossible to give one answer here. All of them are suitable, it all depends on the other parameters you want to achieve.

Something is wrong with the formulation/igredients. Either you have the wrong thickener(s), or too little, or there may be many other reasons.

Water sensitivity test is not performed according to ASTM. This is our procedure described in our internal test method

@@SpektrochemResearchLaboratory OK. I understood... but I have a question, with my difference L, what am I evaluating or what information does it give me?

What you wrote is not entirely true. Most high-quality acrylic dispersions today are resistant to high shear forces, however, during let down, the anchor mixer used in the video does not cause shear because it involves using a dispersing disc, which causes potential shear. High shaft speeds when using an anchor mixer do not cause a problem here. So everything is fine. A bigger problem is the frequent addition of polymer dispersions to mill-base, which causes disturbances in the surfactants present in the dispersion and their coagulation, therefore polymer dispersions must not be added to mill-base, only mill-base to polymer dispersions.
