DISPERBYK-2026

Wetting and dispersing additive for solvent-borne coil coatings, wood and industrial coatings and pigment concentrates, for stabilising a multitude of organic and inorganic pigments and matting agents. Particularly suitable for acid-catalysed polyester/melamine systems and high baking temperatures. The additive deflocculates pigments by means of steric stabilisation. It also generates a uniform electrical charge in the pigment particles. The resulting repulsion effect and the steric stabilisation prevent any co-flocculation which leads to non-floating colouring in pigment blends. As a result of the small particle size of the deflocculated pigments, high levels of gloss can be achieved and the colour strength is improved. In addition, the transparency is increased in transparent pigments and the hiding power in opaque pigments. The viscosity is reduced. In this way, the flow characteristics are also improved and a higher pigment load can be achieved. DISPERBYK-2026 can be used with organic and inorganic pigments. It stabilises titanium dioxides, irrespective of the surface treatment, and enables a high degree of whiteness. As a result of the narrow molecular weight distribution of the additive, it has a broad compatibility in many different binder systems. The additive offers excellent compatibility, especially in polyester resins. DISPERBYK-2026 is suitable both for the production of pigment concentrates as well as for co-grinding. In pigment concentrate systems, the additive can be used to achieve a considerable reduction in viscosity. In acid-catalysed and acid-curable systems, the additive does not have a negative influence on the drying properties. In baking systems, no yellowing is evident even at higher temperatures. Especially recommended for coil coatings and also suitable for industrial and wood coatings.
