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.
