EFKA PU 4020
EFKA PU 4020
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
- 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® high-molecular-
weight polymeric dispersants.
Applications
EFKA PU 4020 was developed as a general dispersing agent for all low-aromatic or aromatic-free solvent-based paints from high-performance industrial coatings to normal decorative paints. It gives excellent performance in epoxy systems as well and can also be used in universal solvent-based pigment concentrates.
