EXOdis PC40A is a polymer anionic dispersant intended for paint products. It is supplied in the form of 40% aqueous solution of ammonium salt of polyacrylic acid. The product is a clear or lightly murky yellow liquid.
EXOdis PC40A has very good dispersing properties, especially in case of titanium white and mineral fillers. The product is compatible with widely used acrylic dispersions, styrene and acrylic dispersions, as well as with homo- & copolymers of vinyl acetate. It is also highly compatible with the most popular rheology modifiers. EXOdis PC40A is better in improving water resistance of paint coats than sodium salt of polyacrylic acid (EXOdis PC40).
The application of EXOdis PC40A significantly decreases the viscosity of aqueous suspensions of titanium white and mineral fillers. Therefore, the product allows large amounts of pigment and/or fillers to be efficiently introduced into the water system. Even low concentrations of EXOdis PC40A provide paint products with very good stability. EXOdis PC40A has a positive impact on the compatibility of pigments in colour products.
EXOdis PC40A is also used as a basic dispersing agent in waterborne decorative paints. Thanks to its low content volatile organic compounds (“VOCs”), the product may be used to create paint formulations in compliance with Directive 2004/42/EC.
The recommended level of use in waterborne paints is 0.1 – 0.6% (w/w).
