ABSTRACT:
Method for applying an aqueous benzyl alcohol paint strippling composition to the surface of a high strength steel substrate or of an assembly containing high strength steel components, such as steel fasteners on the surface of aircraft assemblies, while minimizing the effect of hydrogen-induced embrittlement, hydrogen-induced cracking and corrosion normally caused by aqueous benzyl alcohol. The invention comprises applying a liquid silane to the surface of the steel substrate or components immediately before and/or as an ingredient of a novel aqueous benzyl alcohol composition of the present invention which contains from about 1% to 10% by volume of the liquid silane.
