EFKA® FA 4609

Dispersing agent for solvent-based pigment concentrates

EFKA FA 4609 is a polymeric wetting and dispersing agent with acidic groups. It shows outstanding performance in dispersing and stabilizing inorganic pigments, particularly titanium dioxide. In combination with a universal solvent based grinding resin like LAROPAL A 81, low mill base viscosities with reduced pseudo plastic flow behavior can be achieved. Furthermore, EFKA FA 4609 is highly suitable to disperse iron oxide pigments. This product is suitable for many coating systems, such as automotive OEM and refinish coatings, solvent-based industrial coatings, coil coatings, especially TiO2, and wood coatings.

Product highlights

  • Strong reduction of mill base viscosity
  • Improved rheological behavior
  • High pigment loading
  • Broad compatibility in a wide range of resin systems
  • Suitable for high gloss systems
  • Identical to the market standard in tested systems
