Efka® PX 4330



EFKA® PX 4330 is a high-molecular-weight dispersing agent. It is made by the Controlled Free Radical Polymerization (CFRP) technology, which allows producing polymeric dispersants with defined polymer architecture and a low poly-dispersity index. EFKA® PX 4330 is suitable for stabilizing pigments in solvent-based coatings. This product, due to the very wide compatibility in most current systems used in solvent-based coatings, is especially suitable for the production of Resin Minimal Pigment Concentrates (RMPC) in combination with a multi compatible dispersing resin.


  • Solvent-based industrial and decorative coatings
  • Made by CFRP technology
  • Excellent (broad compatibility) for industrial colorants (pigment pastes) in combination with grinding resins
  • Excellent stability against flooding and flocculation
  • Allows high color strength
  • Universal character
  • Strong viscosity depressing effect
