摘要:
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.
摘要:
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.
摘要:
Cleaned metal surfaces are coated with an aqueous anti-corrosion treatment. The anti-corrosion treatment includes an organofunctional silsesquioxane and a fluoro metallic acid such as H 2 TiF 6, H 2 ZrF 6, as well as others and blends. The metal surface can be rinsed immediately after coating, making this anti-corrosion treatment suitable for preparing a metal surface for electrocoating.
