Fast-Acting Rubber-To-Coated-Aluminum Adhesive

Cyanoacrylate adhesive used to join rubber to coated aluminum easier to apply and more effective. One-part material applied in single coat to aluminum treated previously with epoxy primer and top coat. Parts mated as soon as adhesive applied; no drying necessary. Sets in 5 minutes. Optionally, accelerator brushed onto aluminum to reduce setting time to 30 seconds. Clamping parts together unnecessary. Adhesive comes in four formulations, all based on ethyl cyanoacrylate with various amounts of ethylene copolymer rubber, poly(methyl methacrylate), silicon dioxide, hydroquinone, and phthalic anhydride.
