Influence of hydrophobically modified HEC on the viscosity of latex paints

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”

The flash point of coalescing agents for water-borne 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”

The range of laboratory tests used to evaluate stain resistant latex 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”

Determination of pot-life of 2K WB epoxy paints according to ISO 9514

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”

Volume solids in paints. Why is it considered very important almost only on the NAFTA paint market?

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?”

ASTM D4213 – when the 1st class of EN 13300 is not enough for quality of latex paint

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”

Freeze-thaw additives in latex paints on the Canadian market

Latex paints are generally not resistant to freezing temperatures. As a result of ice formation, polymer dispersions present in paints are destroyed. The need for heated transport, storage in heated warehouses is standard during periods of intense winter in countries such as Canada. However, there remains the problem of paint handling and heating failure inContinue reading “Freeze-thaw additives in latex paints on the Canadian market”
