DISPERBYK® -190

DISPERBYK® -190 by BYK is a solution of a high molecular weight block copolymer with pigment affinic groups. Acts as wetting and dispersing agent. It does not contain organic solvents and deflocculates pigments through steric stabilization of the pigments and fillers. DISPERBYK® -190 reduces viscosity, subsequently, leveling is improved and higher pigment loading is possible. It is recommended for aqueous adhesives and suitable for epoxy, PUR systems. Its recommended levels are 20 - 30% inorganic pigments, 10 – 12% titanium dioxide, 30 – 75% organic pigments, 130 – 150% carbon blacks and 1 – 3% fillers.
