DISPERBYK-2055 is a high molecular-weight wetting and dispersing additive with a solids content of 100 %. It is liquid and has a good processing viscosity. DISPERBYK-2055 can be used in systems of varying polarity, from low-polarity solvent-borne systems, including air-drying alkyds, alkyd/melamine resins, nitrocellulose, 2-pack polyurethanes, acrylic/melamine resins, and UV-curable coatings, through to aqueous systems. In solvent-borne systems, it can be used with or without grinding resin, whereas in aqueous formulations, the best results are achieved with binder-free grinds. DISPERBYK-2055 is the perfect additive for co-grinds, where different pigments are typically ground together and for pigment concentrates. With DISPERBYK-2055, it is possible to produce binder-containing or binder-free pigment concentrates that can be used in aqueous and solvent-borne coatings. DISPERBYK-2055 stabilizes inorganic pigments, including titanium dioxide and transparent iron oxides, organic pigments, carbon blacks, effect pigments, fillers, and matting agents. DISPERBYK-2055 does not negatively impact coating adhesion (not even when applied directly to metal), water- and chemical resistance, or hardness and yellowing resistance. DISPERBYK-2055 has an excellent price-performance ratio.

BYKJET-9175 is a high-performance wetting and dispersing additive designed to optimize organic pigment and dye stabilization in aqueous inkjet inks. Utilizing advanced polymerization technology, it enhances ink stability, color strength, and flow behavior, supporting efficient processing and superior print quality.

BYK-152 is an ammonium polyacrylate-based dispersing additive designed for pigment stabilization in aqueous emulsion paints and adhesives. It enhances gloss, reduces viscosity, and improves storage stability without stabilizing foam. As an ammonium salt, it minimally affects curing and water resistance compared to metal salts. BYK-152 is available exclusively in the North American market.

DISPERBYK-2205 is a high-performance wetting and dispersing additive designed for solvent-borne and solvent-free coatings, printing inks, and inkjet inks, effectively stabilizing both inorganic and organic pigments.
