Abstract: The present invention provides a metallic member reinforcing epoxy-based adhesive coating. The epoxy-based adhesive coating including a first epoxy material containing approximately 25% solids by weight and a second curative material containing about 32% solids by weight. According to one aspect of the present invention, the first epoxy offered suitably includes about 3% to about 35% liquid Diglycidylether of Bisphenol-A, about 35% to about 60% solid Diglycidylether of Bisphenol-A, about 10% to about 30% Novolac-Epoxy, and about 5% to about 18% Solid Carboxy—Terminated Acrylonitrile—Butadiene Rubber, and the second curative material suitably includes about 0% to about 100% 4,4′-Diaminodiphenylsulfone, about 0% to about 100% 3,3′-Diaminodiphenylsulfone, and about 0% to about 0.2% Chromium octoate.

Abstract: Apparatus and process for continuous surface preparation of metal materials. The metal material is grit blasted with a mixture of fine particles of aluminum oxide in air and water. The metal material is rinsed with water to remove the grit. The metal material is subjected to a caustic solution of sodium hydroxide and then rinsed with water to remove the caustic solution of sodium hydroxide. A sol-gel coating is applied to the metal material and the water portion of the sol-gel coating is evaporated. A liquid adhesive coating is applied to the sol-gel coating on the metal material and the solvent portion of the adhesive coating is evaporated.

Abstract: A method of treating a metal material to increase the metal's ability to adhere to other objects is provided. The metal material is prepared to receive a sol-gel solution coating. A sol-gel solution is prepared and the sol-gel solution is applied to the metal material. Subsequently, an epoxy-based adhesive coating is applied over the sol-gel solution, thereby creating an adhesive layer on the metal material.
