DISPERBYK®-190 is a wetting and dispersing additive for aqueous systems and pigment concentrates. It is a solution of a high molecular weight block copolymer with pigment affinic groups. This product is especially designed for the production of resin-free, stable pigment concentrates for flood/float-free general industrial aqueous coating systems. For optimum performance, it is recommended that only pigment, DISPERBYK®-190 and water be used for pigment grinds (resin-, amine- and co-solvent-free). DISPERBYK®-190 does not contain organic solvents and therefore is only suitable for aqueous systems.
