Efka® PX 4300

Efka® PX 4300 (Old Name: Efka® 4300) by BASF is acrylic block copolymer-based dispersing agent for high performance organic pigments. It is made by CFRP technology which allows for production of polymeric dispersing agents with defined polymer architecture and low polydispersity index. It offers high color strength, good stability against flooding, floating and flocculation and wide compatibility. It shows strong viscosity-depressing effects. It is suitable for high quality solvent-based coating systems where high dispersing performance with difficult organic pigments is needed. Efka® PX 4300 is recommended for use in automotive OEM and refinish applications.
