DISPERBYK-190

DISPERBYK-190 is a VOC-free wetting and dispersing additive suitable for aqueous systems. It is a solution of a high molecular weight block copolymer with pigment affinic groups. DISPERBYK-190 deflocculates pigments by means of steric stabilization. As a result of the small particle sizes of the deflocculated pigments, high levels of gloss can be achieved and the color strength is improved. The transparency is also increased and the viscosity is reduced. In this way, the flow characteristics are also improved and higher pigment loading is possible. DISPERBYK-190 is especially recommended for producing binder-free, stable pigment concentrates with a pigment content of 30-60 %. These pigment concentrates can be let down with standard aqueous binders.
