Dispersions, Resins and Additives
Efka® PX 4321
Dispersing agent with exceptional viscosity control and broad pigment affinity, including inorganic pigments.
Efka PX 4321 is a dispersant made with Controlled Free Radical Polymerization (CFRP) technology, which results in well-defined polymeric structures. It is highly suitable for resin-free and resin-containing pigment concentrates and it is compatible with a wide range of industrial and automotive resin systems. It provides excellent coloristic properties with high-performance organic pigments, especially when transparency is required.
