Abstract
Abstract The present invention is directed to thermosetting binder compositions for coating, comprising: (I) (1) A non-acidic resinous compound, saturated, molecular weight at least 900, alcoholic hydroxyl content at least 0.2 eq/100 g; (2) a cross-linking agent comprising a non-acidic polyester of a polycarboxylic acid, having more than one beta-hydroxyl ester group per molecule, at least one of components (1) and (2) having an alcoholic hydroxyl functionality of more than 2, and (II) a curing catalyst comprising a transesterification-promoting metal compound which is insoluble in liquid hydrocarbons. These compositions can be used in solvent-based lacquers and paints, in coating powders, aqueous powder suspensions, in aqueous coating compositions for cathodic electrodeposition; for aqueous compositions component (I) (1) is preferably an epoxy resin/amine adduct.
