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. 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.
