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. voir moins | |

Due to its wide compatibility and the combination with a polysiloxane, the following advantages can be achieved: reduced dispersion time and stabilization of the pigment dispersion, prevention of flooding and floating, reduced pigment sedimentation, reduced tendency to 'orange-peel', improved gloss and leveling. This product is a high-molecular weight unsaturated polycarboxylic acids and esters, combined with a compatible organically modified polysiloxane. Efka® FA 4670 is especially suitable to stabilize all kinds of pigments and is applied in solvent-based industrial coatings like: alkyd/amino resin combinations; acrylic polyisocyanate systems; nitro-cellulose systems; polyurethane- and chlorinated polymer systems; and chlorinated polymers. voir moins |
