VOC and solvent-free wetting and dispersing additive for solvent-borne and solvent-free coating systems, floor coatings, and printing inks. Particularly recommended for the manufacture of pigment concentrates with broad compatibility.


Coatings and Printing Inks

DISPERBYK-2155 deflocculates pigments and stabilizes them by means of steric hindrance. It prevents a possible coflocculation, which leads to non-floating coloring in pigment blends. The deflocculating property of the additive results in increased gloss, color strength, transparency or hiding power, and a reduced millbase viscosity.

Recommended Use

Due to its high solids content, DISPERBYK-2155 is particularly suitable for high-solid coating systems and floor coatings. The additive is exceptionally compatible with all standard coating binders such as alkyd resins, cellulose nitrate, polyols, chlorinated rubber, epoxides, and polyurethanes. DISPERBYK-2155 greatly reduces the viscosity of the millbase which enables a higher pigment content in pigment concentrates.
