EFKA® FA 4644

EFKA FA 4644 is a transparent, yellowish liquid additive for pigment dispersion. It reduces the interfacial tension between pigments or extenders and the vehicle. This means reduced dispersion time, stabilization of the pigment dispersion, decreased pigment sedimentation, and increased gloss and improved flow. EFKA FA 4644 is compatible with all solvent or solvent-free coating systems. The pot-life of two-pack systems is not affected.
