This results in: improved gloss and DOI reduced flooding problems higher colour strength EFKA-4400 is an acrylic polymer with significant higher molecular weight compared with the EFKA polyurethane based polymeric dispersants. This gives better deflocculation of organic pigments. Application: EFKA-4400 is mainly used in automotive OEM and refinish topcoats. Incorporation: EFKA-4400 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. Acrylic polymer with significant higher molecular weight compared with other polyurethane based polymeric dispersants: this gives better deflocculation of organic pigments. Should be incorporated in the mill base before adding the pigments.
