EFKA PX 4320 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 4320 is suitable for solvent-based industrial and automotive coatings.

EFKA PX 4320 offers high efficiency in stabilizing pigments and demonstrates a wide compatibility with many resin systems. This makes EFKA PX 4320 ideally suited for use of the concept of Resin-Free Pigment Concentrates (RFPC).

• improves color development with organic pigments
• highly suitable for optimum dispersion of carbon blacks
• viscosity reduction at high pigment concentration in the grinding stage

Applications

EFKA PX 4320 is highly suitable to be used in Resin-Free Pigment Concentrates (RFPC) for a wide range of solvent-based industrial and automotive coatings.
