Method for improving corrosion Resistance of metal Substrates using mixtures of aminosilanes Silanes and multi sililfuncionales; compositions that include such mixtures of aminosilanYou sililfuncionales Silanes and multi Solutions and use of these mixtures for improvement include

摘要

It is a method for Treatment of metal substrates and provide Permanent resistance to corrosion.The method is characterized in that it comprises: (a) provide Crossing a metal substrate; and (b) Implement a durable substratum coating on metal substrate by contacting the metalA Solution containing one or more aminosilanes hydrolysates or partially hydrolyzed,One or more multi sililfuncionales hydrolyzed Silanes or parcialmentehidrolizados ysustancialmente Solvent and solvent removal.The method is particularly suitable for use on surfaces of cold-rolled Steel, zinc, Iron, Aluminum and Aluminum Alloys.Also, these objects are proposed and established in the title.
