DISPERBYK-168

Wetting and dispersing additive for solvent-borne and solvent-free radiation-curable coatings, printing inks and adhesives. The additive deflocculates the pigments and stabilises them by means of steric hindrance. It provides equal electrical charge to the pigment particles. The resulting repulsion and the steric stabilisation prevent a possible co-flocculation, which leads to flood and float-free colour in pigment mixtures. The deflocculating properties of the additive increase gloss, colour strengh, transparency, and hiding power and reduce the viscosity of the millbase. The additive is particularly recommended for UV-curable flexo and offset printing inks. It increases gloss and transparency. DISPERBYK-168 reduces the dispersion time, lowers viscosity and increases colour strength.
