ABSTRACT OF THE DISCLOSURE : This invention relates to a method of treating metallic or oxidic surfaces which are suitable for bonding to polymers such as resol, furan, epoxide or polyurethane resin. This method comprises applying to the surface an aqueous solution comprising a mercaptosilane corresponding to the general formula Image in which R represents an alkyl or alkoxyalkyl radical having from 1 to 8 carbon atoms, R' represents a monovalent hydrocarbon radi- cal having from 1 to 4 carbon atoms, R" represents a divalent hydrocarbon radical having from 1 to 10 carbon atoms, Y is 0 or 1 and x is 0,1, 2 or 3, the radicals represented by R being the same or different when x is greater than 1, oxidizing the mercaptosilane, and drying the surface to obtain the desired treated surface.
