General
Efka® PU 4047 is a polymeric dispersant for stabilizing inorganic and organic pigments. The higher molecular weight of Efka® PU 4047 compared to Efka® PU 4046 gives stronger deflocculation results with some organic pigments and carbon blacks. In spite of its higher molecular weight, Efka® PU 4047 has a wide compatibility with all kinds of resins.
