DISPERBYK 185 is a solvent-free wetting and dispersing additive that is particularly suitable for glycol-free universal pastes. DISPERBYK 185 deflocculates pigments by steric stabilization. The small particle size of the deflocculated pigments can achieve high levels of gloss and improved color strength. Transparency and hiding power also increase and viscosity is reduced. This also improves leveling and enables higher pigmentation levels. DISPERBYK 185 is solvent-free and suitable for the manufacture of alkylphenol-ethoxylate-free and solvent-free universal colorants used in aqueous, solvent-borne and solvent-free systems. The additive provides benefits like reduced viscosity, improved hiding power, transparency and higher pigmentation levels which are highly desirable in applications involving surface coatings, colorants and pigment dispersions.
