Abstract
To prepare a metallic surface for adhesive bonding, surface irregularities and contaminants are removed. This first step is followed by repeated cleaning of the metallic surface with a solvent and testing of the metallic surface for uniformity. Next, new surface material is exposed by blasting or abrading the surface material. Subsequently, the surface is cleaned and again tested for uniformity. Finally, the surface is treated with a silane solution and dried prior to bonding.
