This results in: improved gloss and DOI reduced flooding problems higher colour strength lower viscosity The higher molecular weight of EFKA-4047 compared to EFKA-4046 gives stronger deflocculation results with some organic pigments and carbon blacks. In spite of its higher molecular weight EFKA-4047 has a wide compatibility with all kinds of resins. Pigment concentrates based on EFKA-4047 exhibit low viscosity and can even be used in pure, white spirit-based let-downs. Application: EFKA-4047 is used in high quality industrial coatings such as: automotive topcoats (OEM and refinish), coil coatings and 2-pack polyurethane coating systems, as well as pigment concentrates (see our concept for resin minimal pigment concentrates based on EFKA polymeric dispersants). Incorporation: EFKA-4047 should be incorporated in the mill base before adding the pigments. High molecular weight polymeric dispersant for deflocculation of pigments. Suitable for stabilizing inorganic and organic pigments. Improves gloss and DOI. Reduces flooding problems. Provides high colour strength and low viscosity. Gives strong deflocculation results with some organic pigments and carbon blacks. Wide compatibility with all kinds of resins. Pigment concentrates based on this additive exhibit low viscosity and can even be used in pure, white spirit-based let-downs. Many of the newer types of high solid resin systems or oil-free polyesters, cause significant flocculation problems, which can often be solved by using this additive. Should be incorporated in the mill base before adding the pigments.
