Abstract: The present disclosure relates to a coating composition, comprising: —a resin component containing an epoxy resin and a petroleum resin; —zinc particles in an amount of at least 65 wt.-%, based on the total solid weight of the coating composition; —a metallic salt of phosphorous acid; and —a hardener. In addition, the present disclosure also relates to a multi-part coating form of said coating composition, a method for preparing the coating composition and a substrate coated with the coating composition.

Abstract: The instant application relates to a polysiloxane-based coating composition, comprising: Polysiloxane of formula I wherein each R1 is independently a hydroxyl group or an alkyl, aryl or alkoxy group having up to 6 carbon atoms, each R2 independently is hydrogen or alkyl or aryl group having up to 6 carbon atoms, and n is selected so that the molecular weight for the polysiloxane is 400 to 10000; a non-aromatic epoxide resin having more than one 1, 2-epoxide group per molecule with an epoxide equivalent weight of 100 to 5000; a multi-functional (meth) acrylate monomer; and a cure system comprising at least one alkoxy functional aminosilane. Furthermore, it also relates to a method of coating surface using said coating composition and the substrate coated therewith.
