Efka® PX 4350



Efka® PX 4350 is made by the Controlled Free Radical Polymerization (CFRP) technology, which allows producing polymeric dispersants with defined polymer architecture and a low polydispersity index. Efka® PX 4350 is suitable for solvent-based industrial and automotive coatings. Efka® PX 4350 offers high efficiency in stabilizing pigments and demonstrates a wide compatibility with many solvent-based resin systems.
