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.
