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”
