German technical background VOK- 2155 Wetting dispersant For solvent and solvent-free systems replaces BYK- 2155

German technical background VOK®- Disper 2155

VOC and solvent free wetting and dispersing agent, used in solvent based and solvent-free systems, floor coatings and printing inks. Because of its wide compatibility, it is recommended to be used in the production of pigment concentrate slurry. Its 99.99% active component makes it suitable for high solid content and solvent free systems.

VOK®- Disper 2155 is used to deflocculate and stabilize pigments through steric hindrance. They provide the same charge to different pigments, thus avoiding possible co flocculation of different pigments. Due to the deflocculation of the auxiliary agent, the gloss and tinting power can be improved, the transparency of the transparent pigment and the hiding power of the opaque pigment can be increased, and the viscosity of the color paste can be reduced. Due to The high solid content of VOK®-Disper 2155 is especially suitable for high solid content systems and floor paints, and has a very wide compatibility with all standard paint systems, such as alkyd resin, cellulose, polyol, chlorinated rubber, epoxy and polyurethane. VOK®- Disper 2155 can well reduce the viscosity of color paste, thus increasing the pigment content in color paste.
