EFKA-4047 is a polymeric dispersant for stabilizing inorganic and organic pigments.
This results in:
-improved gloss and DOI
-reduced flooding problems
-higher color 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 exhibits 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). |
