Wettings agents for architectural coatings
Wetting agents/compatibilizers are added to waterborne and solvent-borne coatings to increase the tinting strength and to improve the compatibility with pigments in order to reduce rub-out effects.
Clariant has evaluated its range of wetting agents/compatibilizers for waterborne emulsion paints (high PVC), waterborne acrylic lacquers (low PVC) and solvent-borne alkyd lacquers (low PVC) according to a comprehensive set of parameters.
