Dispex Ultra PX 4575 is a water-based dispersant made by Controlled Free Radical Polymerization (CFRP). This technology allows the synthesis of polymeric dispersants with highly defined polymer architecture and a low poly-dispersity index. Dispex® Ultra PX 4575 is especially suited for the dispersion of pigments in water-borne coatings and colorants.

This material offers high efficiency in stabilizing pigments and demonstrates wide compatibility with many water-based resin systems.

Dispex Ultra PX 4575 is very broad in its compatibility with different water-based resins and pigments and can be used in the following applications:

• for organic and inorganic pigments
• in resin-free pigment concentrations (RFPC)
• in resin containing pigment concentrates
• for water-based architectural in-plant tinters
• for high performance water based paints
