It is a high-molecular weight unsaturated carboxylic acid, combined with a very compatible organically modified polysiloxane. This transparent, slightly brownish liquid 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 polyisocyanate systems (2-pack acrylics), and chlorinated polymers. EFKA® FA 4665 is not compatible with white spirit or paints which are diluted with white spirit. view less | |

This results in reduced dispersion time, stabilization of the pigment dispersion, decreased flooding of pigments, and prevention of hard sedimentation. This product is an alkylol ammonium salt of a high-molecular weight carboxylic acid. EFKA® FA 4671 is suitable for use in low or high-polarity solvent systems as well as water-based coatings. It is used to reduce flooding and settling in non-polar systems e.g. air drying alkyd paints. It is an effective anti-settling agent in wash and shop primers. It improves the color acceptance of tinting bases in white latex paints, resulting in higher pigment efficiency. view less |
