Dispersions, Resins and Additives

Control Free Radical Polymerization (CFRP)

The Additives' Control Free Radical Polymerization (CFRP) technology is used to create high-performance dispersants for difficult-to-disperse organic and inorganic pigments. This technology leverages the advantages of a special chemistry to achieve narrow molecular weight distributions and well-defined polymer architectures. The CFRP dispersants are designed to improve pigment wetting, reduce particle size, and stabilize dispersions; the technology is particularly useful in applications requiring high-performance coatings and inks, where precise control over polymer properties is essential.

Key benefits:

Enhanced viscosity control
Improved strength and opacity
Better photo stability
Higher pigment delivery efficiency
