Abstract

A method of applying a layer of exogenous inorganic oxide to a metal article which method involves heating a coating of a coupling agent for a temperature and for a time sufficient to convert the coating to a layer of exogenous inorganic oxide. Also a method of adhering a metal article to an adhesive and/or a composite and a method of adhering a metal article to a substrate.

Independent Claims | See all claims (2)

  1. 1. A method for adhering a metal article to an adhesive and/or a composite, which method comprises the steps of:(a) coating at least a portion of the surface of the article with a coupling agent that is capable on heating of forming exogenous inorganic oxide;(b) heating the coated surface at a temperature and for a time sufficient to convert the coating to a layer of exogenous inorganic oxide; and(c) adhering the metal article at said layer of exogenous inorganic oxide to the adhesive and/or composite,wherein the adhesive and/or composite comprises a resin comprising a mixture of Bisphenol A diglycidylmethacrylate and triethyleneglycol dimethacrylate.
  2. 2.2. A method for adhering a metal article to a substrate by way of an intermediate layer of adhesive, which method comprises the steps of:(a) coating at least a portion of the surface of the article with a coupling agent that is capable on heating of forming exogenous inorganic oxide;(b) heating the coated surface at a temperature and for a time sufficient to convert the coating to a layer of exogenous inorganic oxide;(c) adhering the article at said layer of exogenous inorganic oxide to an intermediate layer of adhesive composite; and(d) adhering the substrate to the metal article by way of the intermediate layer,wherein the adhesive comprises a resin comprising a mixture of Bisphenol A diglycidyl-methacrylate and triethyleneglycol dimethacrylate.
