Abstract

A rinse solution for the treatment of conversion-coated metal substrates for approving the adhesion and corrosion resistance of siccative coatings comprising an aqueous solution of a group IVA metal ion selected from titanium, hafnium and mixtures thereof, optionally with other groups IVA metal ions, and an organosilane selected from the group consisting of methyltrimethoxysilane, phenyl trimethoxysilane and, for hafnium-containing compositions, 3-glycidoxypropyltrimethoxysilane.
The group IVA metal ion concentration is selected to provide a pH in the range from 2.0 to 9Ø The solution is applied to a conversion-coated substrate.
