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.
