EFKA PX 4340 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 4340 is suitable for stabilizing pigments in solvent-based high-performance coatings such as automotive OEM and refinish coatings. It has an excellent affinity for organic pigments, especially where high transparency is required.

• improves color development and transparency with organic pigments
• highly suitable for optimum dispersion of transparent iron oxides
• viscosity reduction at high pigment concentration at the grinding stage
• gives excellent gloss to the final coating

Applications

EFKA PX 4340, due to the very wide compatibility in most current systems used in solvent-based coatings, is especially suitable for the production of Resin Minimal Pigment Concentrates (RMPC) in combination with a multi compatible dispersing resin.
