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.
