General
EFKA® PX 4300 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 4300 is suitable for stabilizing pigments in solvent-based coatings and for those where high performance of difficult organic pigments is needed, e.g. automotive coatings (OEM and refinish).
