Abstract: A coating composition for use on a cleaned but untreated metal surfaces includes a liquid polymerizable coating composition such as a urethane paint, or the like, blended with an organofunctional silane. The organofunctional silane can be a bis-functional monomeric or an oligomeric silane such as a silsesquioxane. The composition can be applied directly to an untreated metal surface. The silane in the coating composition improves adhesion of the coating composition and deters corrosion.

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. 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.

Abstract: A coating composition containing a resin; a curing agent; a catalyst; and a hydrolyzed bis-amino silane provides excellent adhesion between the substrate and the coating.

Abstract: The present invention provides for a slow-release inhibitor that is applied to a metal surface, such as by way of a paint or primer coating, for corrosion control of the metal. An exemplary embodiment of the slow-release corrosion inhibitor includes a water-soluble particle, or pigment, and an organic polymeric film that encapsulates the particle. This water-soluble particle may be either organic or inorganic and, preferably, is non-carcinogenic and non-toxic. An additional water-soluble particle having an encapsulating, organic polymeric film further may be provided along with a water-soluble, organic compound to form the corrosion inhibitor. The polymeric film(s) are of a desired hydrophobicity and permeability to permit, upon interaction of the particle(s) with water, controlled diffusion of particle ions therethrough.

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.
