Efka® FA 4665
General
EFKA® FA 4665 is a high-molecular weight unsaturated carboxylic acid, combined with a very compatible organically modified poly siloxane, helps to prevent interfacial tension between the hydrophilic pigments/extenders and the binder. It is especially suitable for medium to high-polarity binder systems, for example: alkyd/amino resin combinations, nitro-cellulose systems, polyurethane- and chlorinated polymer systems, acrylic poly isocyanate systems (2-pack acrylics), and chlorinated polymers. EFKA® FA 4665 is not compatible with white spirit or paints which are diluted with white spirit.
Benefits
- Reduced pigment sedimentation
- Reduced dispersing time
- Reduced tendency to “orange peel”
- No formation of Bénard cells
- Prevent interfacial tension between hydrophilic pigments/extenders and binder
- Improved gloss and slip
- Stabilization of the pigment dispersion
- Prevention of flooding and floating
