EFKA® PU 4020

Aromatic-free dispersing agent for solvent-based industrial coatings and decorative coatings and colorants.

EFKA® PU 4020 is a polymeric dispersant for stabilizing inorganic pigments including carbon blacks. It also has an excellent performance in many organic pigments. This results in reduced grinding time, improved gloss, prevention of flooding and floating problems, and higher color strength. Due to its particularly good combination of price and performance, EFKA® PU 4020 is a very attractive substitute for conventional wetting and dispersing agents. It is possible to mix combinations of inorganic pigments stabilized with EFKA® PU 4020 and organic pigments stabilized with other EFKA® highmolecular-weight polymeric dispersants.
