Abstract
Curable, saturated polyester resins and epoxy resin cross-linking agents therefor, in association with an at least divalent metal oxide and a cross-linking catalyst, are useful binders for mechanically improved powder paints, e.g., those typically applied to metallic substrates by electrostatic deposition or fluidized bed spraying.
Claims39
A powdery composition of matter comprising (i) a cross-linkable, carboxylated, saturated polyester resin;
- (ii) an epoxy resin cross-linking agent for the polyester (i), (iii) a metallic oxide, the metal cation of which is selected from the group consisting of zinc, magnesium, cadmium, iron (II) and alkaline earth;
- and (iv) an epoxy ring-opening catalyst.
