Abstract
The invention relates to a method of improving corrosion resistance of a metal. The method comprises applying a solution containing one or more amino silanes in admixture with one or more multi-silyl-functional silanes to a metal substrate in order to form a long term corrosion resistant coating. The method is particularly suitable for use on cold-rolled steel, zinc, iron, aluminium and aluminium alloy surfaces.
