CRAYVALLAC® EF 30P is a low molecular weight styrene-maleic anhydride copolymer with an approximate 3:1 mole ratio. It is used as a matting agent in epoxy or epoxy/polyester powder coating formulations. Excellent results are obtained by combining CRAYVALLAC® EF 30P with REAFREE 6489-TS, Carboxylated Polyester resin. The very good colour stability of formulations containing CRAYVALLAC® EF 30P as matting additive, enables the production of low gloss white and pale colour paints. CRAYVALLAC® EF 30P has been developed specifically to provide matting effect in powder coatings.
