Abstract:
A sol suitable for surface treatment of a metal for improving adhesion, comprising:a) a dilute sol having about 1 vol % of an alkoxyzirconium in a carrier containing alcohol, wherein the zirconium in the sol covalently bonds to the metal to form a metal-to-organic interface on the metal surface;b) about 2 vol % of a glycidoxysilane coupling agent dissolved in the carrier and adapted for covalently bonding through the glycidoxy moiety with an epoxy adhesive; andc) an effective amount of an organic acid, if the carrier contains water, for acting as a catalyst and as a hydrolysis rate stabilizer for the alkoxyzirconium.
