ABSTRACT:
A method of bonding a plurality of articles together with an organic adhesive by using a primer that provides increased crack propagation resistance without the use of organic solvents. The method comprises reacting aluminum, titanium silicon, iron, or zirconium with HBr or HI. The reaction product is oxidized with a water soluble oxidizing agent to form a hydrosol. The hydrosol is then mixed with an organofunctional silane to form the primer. The primer is applied to the surface of an adherend prior to the application of adhesive.
