DISPERBYK® 170

1 of 58 products in this brand
DISPERBYK® 170 is a wetting and dispersing additive for solventborne coil and industrial coatings. It is particularly effective in acid-catalyzed and acid-curable coating systems, offering high color strength, high pigment loading, and excellent gloss. This additive is compatible with melamine formaldehydes and polyvinylidene fluoride (PVDF) resins, making it suitable for top coats, polyester coatings, and solventborne coatings. It reduces viscosity, improves flow, and provides high transparency, ensuring enhanced performance in industrial coatings. DISPERBYK® 170 is also compatible with polyurethane (PU) formulations.

Key Features
  • The additive deflocculates pigments by steric stabilization.
  • As a result of the small particle sizes of the deflocculated pigments, high levels of gloss can be achieved and the color 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 higher pigment loading is possible.
  • DISPERBYK-170 has an extremely high molecular weight and this results in the outstanding stabilization of inorganic and organic pigments.
