Dispersing agent for industrial coatings and transportation topcoats with strong viscosity depression

EFKA^® PA 4401 is a modified polyurethane for stabilizing inorganic and organic pigments with strong viscosity depressing properties. It improves gloss, reductions of flooding problems and higher color strength. This product is broadly compatible – from low- to high-polarity systems, including nitrocellulose. Care should be taken with EFKA^® PA 4401 because of its tendency to yellowing and gelling when combined with chlorinated polymers. It also has a tendency to yellowing when combined with solvent-free epoxies. EFKA^® PA 4401 is used for all kinds of high-quality solvent-based industrial coatings including automotive topcoats as well as pigment concentrates. It shows excellent viscosity depression for industrial colorants in combination with grinding resins such as LAROPAL^® A 81.
