Abstract
A method of bonding a plurality of articles together with an organic adhesive by using a primer that provides increased crack propogation resistance without the use of organic solvents. The method comprises reacting aluminum, titanium, silicon, iron, or zirconium with HBr or HCI. The reaction product is oxidized with a water soluble oxidizing agent to form a hydrosol. The hydrosol is applied to the surface of a metal article prior to the application of adhesive.
