Dispersions, Resins and Additives
Efka® FA 4666
Dispersing agent for polyurethane systems and stoving enamels with strong anti-settling effect.
Efka FA 4666 is a high molecular weight unsaturated carboxylic acid that prevents interfacial tension between the hydrophilic pigments and the binder. This wetting and dispersing additive reduces dispersion time and pigment sedimentation, prevents flooding/floating and stabilizes pigment dispersion. Efka FA 4666 is especially suited for medium to high-polarity binder systems, for example: alkyd/amino resin combinations, nitro-cellulose systems, polyurethane systems, acrylic polyisocyanate systems (2-pack acrylics) and chlorinated polymers.
