METHOD OF APPLYING SILANES TO METAL IN AN OIL BATH CONTAINING A CONTROLLED AMOUNT OF WATER
First Claim
1. A method of applying a silane coating onto a metal substrate comprising contacting said metal substrate with an oil mixture, said oil mixture comprising a blend of an oil, and an organofunctional silane wherein an amount of water effective to improve the adhesion of said organofunctional silane to said metal substrate is added to said oil mixture.

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.
