Abstract:

A silane surface preparation for on-aircraft adhesive bonding of aluminum, known as the grit-blastsilane GBS process, has been optimized. It consists of abrasion using 3M Company Scotch-BriteR pads, aluminum oxide grit blast, and application of an epoxy-functional organosilane coupling agent hydrolyzed in water. The surface preparation has advantages for on-aircraft repair since it does not require the use of acids.
