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.

Siloxane oligomer treatment for metals

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.

Silane compositions and methods for bonding rubber to metals

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.

Slow-release inhibitor for corrosion control of metals

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.

Silane coating compositions and methods of use thereof

A coating composition of oil and organofunctional silane is provided for the treatment of metal substrates. The coating composition features at least 80% by weight of oil and 0.5% to 10% by weight of organofunctional silane. The organofunctional silane includes a polysulfide silane, and the preferred metal substrate is a tire cord. When a tire cord is coated with the coating composition, it allows a tire to be formulated with lower sulfur levels and without cobalt.

Coating composition of oil and organofunctional silane, and tire cord coated therewith

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.
