General
EFKA® SL 3257 is a solvent-free, 100% active, polyether modified polysiloxane, for use in inks, coatings and paints. EFKA® SL 3257 exhibits excellent substrate wetting and reduction of surface tension of the liquid film. It is compatible with a wide range of resins and provides slip modified surfaces that are conducive to recoatability. Additionally, EFKA® SL 3257 has been found to improve gloss, scratch resistance and leveling of coatings, and provides very efficient reduction of COF (coefficient of friction).
