Sustainable development and the circular economy is not a vision of the future, but the present in the perception of raw materials, also for the production of latex paints. Modifications of the formulations to make them more ecological is not only the elimination of VOC / SVOC, but a real concern for resources in theContinue reading “Washability of low sheen paints based on VAE-emulsion from renewable resources”
Mineral thickeners (attapulgites, smectites) form a gel with water after the water penetrates the lamellar layers. The created colloidal form turns out to be effective to varying degrees as a thickener in latex paints. The slide below shows that in some cases of mineral thickeners, the obtained rheological properties may depend on the water withContinue reading “Influence of water used for the production of paint on the hydration of mineral thickeners”
Replacing polymer dispersion in recipes is a frequent procedure that precedes the market situation, e.g. lack of raw materials, the need to optimize prices or quality reasons, e.g. the desire to modify the formulation to improve the parameters of latex paint. Not every pure acrylic (PA) polymer dispersion brings appropriate properties to the formulation, suchContinue reading “Pure acrylic latex plug and play replacing in the formulations. Not so obvious”
Cellulose ethers are an inseparable element of dispersion paints, especially with medium-high and high PVC where the proportion of polymer dispersion is not too high. They are one of the most commonly used wall and ceiling dispersion paint thickeners on the EMEA and Asia-Pacific markets. One of the basic and very common cellulose thickeners isContinue reading “Influence of hydrophobically modified HEC on the viscosity of latex paints”
Flash point is a parameter that is usually associated first with solvents and solvent-based paints. Flammability pictograms are usually found on such products. It should also not be forgotten that the coalescents present in many water-borne paints are also organic compounds showing vapor pressure, which under appropriate conditions show a flash point. These tests areContinue reading “The flash point of coalescing agents for water-borne paints”
Wall paints in terms of stain resistance are experiencing their extraordinary growth. However, not all companies have properly prepared formulations yet, because the preparation of paints that will be resistant to everyday stains and enable their easy removal is extremely difficult and requires extensive knowledge in the field of raw materials and tests to verifyContinue reading “The range of laboratory tests used to evaluate stain resistant latex paints”
Two-component paints (or multiple-component paints) require the addition of a cross-linking agent prior to application. However, it is very important to know about the time the paint should be used up after mixing with the hardener or other recommended crosslinking ingredient. Often, in two-component paints, the determinant is an increase in viscosity that prevents furtherContinue reading “Determination of pot-life of 2K WB epoxy paints according to ISO 9514”
Obtaining hiding power by appropriate preparation of the formulation with the use of volume solids is crucial today to meet market expectations in terms of coverage and compliance with the Eco-label criteria, which define the maximum amount of titanium dioxide pigment used in the coating. But why is attention not so much attached to thisContinue reading “Volume solids in paints. Why is it considered very important almost only on the NAFTA paint market?”
More and more people, not being professional painters, decide to change the color of their homes. Inspired by friendly low-VOC or zero-VOC latex paints, as well as popular Dulux paint ads, they paint a room in one afternoon without covering most furniture or floors with protective film, or not covering them at all. In orderContinue reading “Paint spattering on laboratory tests by ASTM standards. Precise and repeatable”
IntroductionThe standard adopted since 2001 to classify the scrub resistance of wall paint coatings in Europe is EN 13300. It defines 5 classes depending on the thickness loss of coatings after 40 or 200 cycles, determined in accordance with ISO 11998. Thanks to this method, many paints on the European market can be well characterizedContinue reading “ASTM D4213 – when the 1st class of EN 13300 is not enough for quality of latex paint”
