BASF’s Performance and Formulation Additives announced Efka PX 4720, a new high‑performance dispersing agent designed for ultra‑matte, solvent‑free UV coating formulations. The launch was made at the American Coatings Show 2026.

Efka PX 4720 is developed using Controlled Free Radical Polymerization (CFRP) technology, enabling precisely defined acrylic block copolymers. 

Designed for 100% solvent‑free radiation‑curing coating systems, Efka PX 4720 supports formulators in achieving ultra‑matte performance without compromising stability or processability. 

This innovative structure delivers strong viscosity reduction, high matting efficiency, and excellent formulation stability, even at very high silica matting agent concentrations.

Typical applications include industrial coatings, furniture and flooring finishes, as well as 3C coatings.
