Efka® FA 4666



EFKA® FA 4666 is a high molecular weight unsaturated carboxylic acid that prevents interfacial tension between the hydrophilic pigments/extenders and the binder. This wetting and dispersing additive reduces dispersion time and pigment sedimentation, prevents flooding/floating and stabilizes pigment dispersion. This low-molecular-weight dispersing agent is especially suited for medium to high-polarity binder systems, for example: alkyd/amino resin combinations, nitro-cellulose systems, polyurethane systems, acrylic poly isocyanate systems (2-pack acrylics) and chlorinated polymers.
