Speciality
DISP 406 has excellent wetting ability of pigments during dispersion. It could avoid color separation effectively when combining titanium dioxide with other pigments in paints.
DISP 406 contains a small quantity of a polysiloxane copolymer that could improve flooding and floating behavior and has which has no negative influence on the appearance of the coating.
Application System and Dosage
DISP 406 is recommended for alkyd systems, acrylic systems, amino baking varnishes, 2K polyurethane and epoxy systems. Usually, it is recommended to introduce the additive before the dispersion stage during the manufacture with 0.5% to 2% dosage upon inorganic pigments and with 10% to 30% dosage upon organic pigments.
