  • Coating composition of oil and organofunctional silane, and tire cord coated therewith
    Patent number: 7964286
    Abstract: 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.

  • METHOD OF APPLYING SILANE COATING TO METAL COMPOSITION
    Publication number: 20100160544
    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.
