PAT-ADD DA 932

PAT-ADD DA 932 by PATCHAM FZC is polymeric polyurethane with cationic pigment affinic groups. Acts as a dispersing agent. It results in extremely low viscosity and high transparency properties. Exhibits strong adsorption properties onto a wide variety of pigment surfaces, contributing to best dispersion stability, low viscosity pigment dispersions and high transparency fir fine particle sized pigments. It is extremely effective for furnace carbon blacks, for extreme jet, blue undertone. Provides excellent color development. Used in wood coatings, repair refinishes, general industrial coatings, solvent-borne paints and pigment concentrates. The optimal amount of PAT-ADD DA 932 to be used is system related, but generally is between 10 and 15% PAT-ADD DA 932, calculated on the total weight of pigment concentrate. If used in ready mixed paints, dosages of approx. 1 to 4% are suggested. For carbon blacks a dosage of 20 to 60% (active ingredient) on pigment is recommended. It is a REACH compliant.
