Scotch-Weld Instant Adhesive

3M(TM) Scotch-Weld(TM) Instant Adhesive CA40 HV1 Clear, 1 lb, 1 per case Bottle A high-strength cyanoacrylate adhesive. It is a higher viscosity, slightly slower setting version of Scotch-Weld CA40. It has particularly good adhesion to many difficult to bond substrates, such as aluminum, EPDM rubber, and flexible vinyl. Scotch-Weld CA40H exhibits good resistance to soap solutions and isopropyl alcohol. Its high viscosity helps prevent run off during application, and its slower set time allows additional time for proper alignment of parts.
