A method for the treatment of metal surfaces with a mixture of vinylsilanes and multi silylated functional silanes

摘要

The present invention relates to a method of treating a metal substrate to provide permanent corrosion resistance. The method comprises applying a solution containing one or more vinyl silanes in admixture with one or more multi-silyl-functional silanes to a metal substrate in order to form a coating. The method is particularly suitable for use on zinc coated surfaces.
