Abstract:
A metal-resin composite comprises a metal substrate with concavities in the surface, a first coating layer on the surface of the metal substrate, a second coating layer on the first coating layer, and a third coating layer on the second coating layer. The first coating layer fills the concavities and covers the surface of the substrate.
Abstract:
The present invention refers to a method for metallizing a plastic surface of a plastic article having at least a part thereof made from a support comprising a supporting material and an electroless plating promoter. The method comprises the steps of: 1) gasifying the plastic surface to expose the electroless plating promoter; and 2) electroless plating a layer of copper or nickel on the plastic surface, followed by electroplating or a second electroless plating to form a metallized layer on the plastic surface. The electroless plating promoter includes one or more members selected from a group consisting of multicomponent oxides selected from a group consisting of Cu/Fe/Mn, Cu/Fe/Al and/or Cu/Fe/Al/Mn multicomponent oxides.
Abstract:
A coating composition, a composite prepared by using the coating composition and a method for preparing the composite are provided. The coating composition includes a solvent, an adhesive, and a catalyst precursor including at least one selected from a group consisting of SnO 2 , ZnSnO 3 and ZnTiO 3 .
