General
high-molecular-weight dispersing agent
Efka® PU 4010 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
• higher color strength
Due to its particularly good combination of price and performance,Efka® PU 4010 is a very attractive substitute for conventional wettingand dispersing agents.
It is possible to mix combinations of inorganic pigments stabilized with Efka® PU 4010 and organic pigments stabilized with other Efka® highmolecular-weight polymeric dispersants.
