Abstract: Cleaned metal surfaces are coated with an aqueous anti-corrosion treatment. The anti-corrosion treatment includes an organofunctional silsesquioxane and a fluoro metallic acid such as H2TiF6, H2ZrF6, as well as others and blends. The metal surface can be rinsed immediately after coating, making this anti-corrosion treatment suitable for preparing a metal surface for electrocoating.

Abstract: A method of applying to a clean metal surface an aqueous solution comprised of a small percentage of organofunctional siloxane oligomers. The organofunctional siloxane oligomers used in this method include silsesquioxanes. The organofunctional siloxane oligomers are applied to a metal surface prior to the application of a topcoat and function to inhibit corrosion of the metal surface.
Abstract: Compositions and methods for treating metal substrates and/or bonding metal substrates to polymeric materials, such as rubber, are provided. The compositions include at least one substantially hydrolyzed amino silane and at least one substantially hydrolyzed sulfur-containing silane Optionally, the compositions include a nano-size particulate material. The compositions provide coatings on metal substrates for protecting the metal from corrosion and for adhering rubber-like polymeric compositions to the metal with polymer-to-metal vulcanization conditions less dependent on the coating thickness, and with use of less coating materials.

Abstract: A method of treating a substrate, such as a metal surface, by application of a silane coating composition containing at least one water-soluble or dispersible silane and a polymeric resin, which may be provided as a water-based dispersion of polymeric resin, the polymeric resin being present in an amount less than 10% by weight of the composition to slow the rate of corrosion of the metal surface and/or to promote adhesion of rubber thereto. The at least one silane can include a bis-amino silane, a vinyl silane, a bis-sulfur silane, or mixtures thereof and the polymeric resin may include an epoxy resin, acrylate resin, polyurethane resin, novolac resin, or mixtures thereof. The silane coating compositions may be either water or solvent based.

Abstract: Organofunctional silanes are applied to metal surfaces using an oil bath. Metal is immersed in an oil bath containing approximately 2% silane and an oil dispersible hygroscopic liquid, such as glycerol. In one embodiment, the metal is a tire cord. Water vapor entrained in a carrier gas can also be bubbled into the oil silane bath.

Abstract: Organofunctional silanes are applied to metal surfaces using an oil bath. Metal is immersed in an oil bath containing approximately 2% silane. In a preferred embodiment, the metal is a tire cord. The silane can either be hydrolyzed or unhydrolyzed. The hydrolyzed silanes can be in combination with a water dispersible resin. When the tire cord is coated with silane using the present method, it allows a tire to be formulated with lower sulfur levels and without cobalt.
