| abstract |
A method of treating a substrate, such as a metal surface, by application of a siiane coating composition containing at least one water-soluble or dispersible siiane and a polymeric resin, which may be provided as a water- based dispersion of polymeric resin, the polymeric resin being present in an amount less than 10% by weight of the composition to slow the rate of corrosion of the metal surface and/or to promote adhesion of rubber thereto. The at least one siiane can include a bis-amino siiane, a vinyl siiane, a bis- sulfur siiane, or mixtures thereof and the polymeric resin may include an epoxy resin, acrylate resin, polyurethane resin, novolac resin, or mixtures thereof. The siiane coating compositions may be either water or solvent based. |
