Thank you! Kind regards

You're welcome. We appreciate it.

Thank you for your extremely uplifting comment!

Thank you!

Thank you, Sam. As you have noticed, this is a general overview. A comprehensive publication on the subject will soon be completed.

Sir you not added HEC please you can explain?

@@ibrarpaintconsultantIn this formulation was used mineral thickener as low-shear rheology modifier. Of course, HEC, hmHEC and other cellulose derivatives we use depending on formulation needs, market needs, etc. Presented formulation was without cellulose derivatives.

Respected Mr.Sam. Is mineral thickener cheaper than HEC? Can I use mineral thickener instead of HEC?

@@mohammadjashimuddin703 I believe this question is better answered by the author of this RU-vid post . . . Artur Palasz from Spektrochem. He has practical experience in formulating architectural paints. My knowledge is based on chemistry, theory, and mechanism.

Thank you!

I translated your comment, thanks for your suggestion. In 2023, there will be many guides on the use of test methods as well. Stay tuned.

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.

Thank you

Thanks a lot!

@@SpektrochemResearchLaboratory I want Stain free Paint in Waterbase which additive will use ?

@@businessaks It is not a question of one additive for ensuring stain resistance. You have to reformulate your paint. Ask your local suppliers for the appropriate raw materials

@@businessaks contact us for complete for formulation of stain free paint

Contact us by e-mail, specify exactly what you need and you will receive an appropriate offer from us.

It's even easier when added to grinding. The point is not to make it easier, but to see how the colorant is accepted as post-additive when added as it is with POS-tinting.

@@SpektrochemResearchLaboratory ohoo... Can we add colorant paste at grinding..?

@@albertzacharias9552 Of course. There are no contraindications for this if you want to get slurry in the right color right away.

Exactly what enamel are you thinking about?

@@SpektrochemResearchLaboratory Gloss and Matte enamel , based on alkyd resins

@@talhaimtiaz5517 We work only with formulations based on water-borne binders, in this case alkyd emulsions. On our YT channel you can find video about our service in the area of WB alkyd formulations

@@SpektrochemResearchLaboratory thank you, last one, besides Water-based alkyd are you provide services on water-based epoxy and polyurethane systems,? their formulations and testing

@@talhaimtiaz5517 Yes, but our formulating is dedicated for raw materials manufacturers. We provide laboratory service in area of studying raw materials in various formulations and we test paint and coating samples prepared in our lab, by use of standardized methods to assessment raw material performance (efficiency of doses, comparisons, etc). Please familiarize with our offer on our website and through our videos here

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.

Maybe you are not using the right talc, kaolin and TiO2, ratio between them and PVC, grain size distribution, etc. Not all kaolin or talcum is the same. Take a look at the example of kaolins what the differences between them can be, I recommend reading the article by Artur Palasz PhD, our formulation expert, which was published in PPCJ - here is the link to the e-journal flickread.com/edition/html/free/629ddf57e4517#34

It is one of the most common coalescing agent (TMPDMIB), trade name by Eastman, that is used to lower MFFT in acrylic-based latex paints and styrene-acrylic emulsions. Its dose depends on the set level of MFFT reduction which is determined in accordance with ASTM D2354 using the Rhopoint MFFT-Bar, and then the dose should be verified and the dose should be corrected based on the prepared paints and the LTC (low-temperature coalescence) tests performed to verify that the coalescent dose is appropriate to form a paint film on a porous substrate at low temperatures (below the link to articles on how important it is to properly define MFFT and LTC).

Thanks for your question. Let me answer in English. It is not necessary to increase TiO2, but to perform operations related to the modification of the filler system and balancing the volume solids, PVC, etc.. Here is an example of getting the opacity for yellow color - tinted transparent base *link to our Instagram: instagram.com/p/CtG_n5zti-6/?igshid=MzRlODBiNWFlZA==

Thanks

The gloss in latex paints is closely related to PVC and the proportion of fillers that reduce gloss. An article on gloss and sheen adjustment in latex paints will be published soon, but we don't know yet when the publication date will be (we suspect 2022).

MEG can be used to provide open-time as an OTE-additive, however PG (propylene glycol) is more commonly used. However, due to the classification of PG as VOC, the best solution are dedicated additives that extend drying and wet edge, such as special OTE-additives

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

In the future, yes we can prepare. Thanks for your suggestion.

@@SpektrochemResearchLaboratory thanks

Our lab is able to formulating architectural water-borne latex paints, water-borne epoxy paints, acrylic DTM paints, etc. We are not able to formulating printing inks.

You have to use start point formulations dediceted you your market and case studies to show you interaction between raw materials. Please contact your local raw material suppliers for more technical materials.

Thank you. That's very kind and I appreciate it. If you would like to use our publications to learn, of course I recommend you all my articles in PCI Magazine, European Coatings Journal, PPCJ and participation in conferences where I give lectures on raw materials and formulations (e.g. European Coatings Show in Nuremberg, CTT Summit in Chicago/Lombard, Waterborne Symposium in New Orleans and others).

Please contact by e-mail.

What is your email address

The bestway to formulate tailored paints will be contact with your local distributor of raw materials who offer application lab support, incl. Azelis, IMCD, Univar Solutions, Brenntag, etc.

Please send us official inquiry by e-mail.

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

Sorry but we are not experts in inks. We work in the area of architectural and wood waterborne paints. We are not able to advice you in printing inks.

The video was not intended to show the formulation here. We prepare them for our clients - producers of the raw materials we talk about in the film, and if you cooperate with them, you can receive such a start point formulation.

You can find test results here, on our blog paintlaboratory.wordpress.com/2021/12/16/formulating-premium-class-latex-paints-for-the-us-market/

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.

We are laboratory dedicated to water-borne paints. Unfortunately, we are not able to work with solvent-borne raw materials
