Properties: EFKA-4401 is a polymeric dispersant for stabilizing inorganic and organic
pigments. This results in:
? improved gloss and DOI
? reduced flooding problems
? high colour strength
EFKA-4401 shows a wide compatibility, from low polarity to high polarity
systems, including nitrocellulose.
Care must be taken with EFKA-4401 as it has a tendency to yellowing or
gelling when used in combination with chlorinated polymers. With solvent-free
epoxies it has a tendency to yellowing.
Application: EFKA-4401 is used in all kinds of high quality solvent-based industrial
coatings including automotive topcoats, as well as in pigment
concentrates (see our concept for resin minimal pigment concentrates
based on EFKA polymeric dispersants).
Carbon blacks : 20% of DBP absorption value
Incorporation: EFKA-4401 should be incorporated in the mill base before adding the
pigments.
High molecular weight polymeric dispersant for deflocculation of inorganic and organic pigments. Improves gloss and DOI. Reduces flooding problems. Provides high colour strength. Shows a wide compatibility, from low polarity to high polarity systems. Has a tendency to yellowing or gelling when used in combination with chlorinated polymers, to yellowing with solvent-free epoxies. Can be used in pigment concentrates.
Should be incorporated in the mill base before adding the pigments.
