Description
Efka PU 4010 is a high-molecular-weight polymeric dispersant based on modified polyurethane, developed for stabilizing inorganic pigments — including carbon blacks — as well as many organic pigments in solvent-based systems. It delivers reduced grinding time, improved gloss, prevention of flooding and floating, and higher color strength. With a strong balance of price and performance, Efka PU 4010 is a cost-effective substitute for conventional wetting and dispersing agents, and can be combined with other Efka® high-molecular-weight polymeric dispersants when mixing inorganic- and organic-pigment systems. Evergreen Chemicals supplies Efka PU 4010 as an authorized BASF distributor.

Efka PU 4010 was developed as a general dispersing agent for all solvent-based paints, ranging from high-performance industrial coatings to standard decorative paints. It is also suitable for universal solvent-based pigment concentrates. Efka PU 4010 should be incorporated into the mill base before adding pigments.
