Material Notes:
PERMABOND® 922 is the original allyl cyanoacrylate adhesive. It is a single part, moderate viscosity liquid that will cure rapidly at room temperature when pressed into a thin film between parts. PERMABOND 922 will cure to fixture strength in seconds on most surfaces, and rapidly develops high strength with full cure obtained in 24 hours. The adhesive was specifically designed to meet the high temperature resistance required by certain applications. It provides excellent bond strength to steel, aluminum, and most metal surfaces. The cyanoacrylate will also adhere well to a wide variety of other materials including most types of plastic and rubber. In order to withstand high temperature environments, PERMABOND 922 was designed with a secondary curing mechanism that is activated at temperatures higher than 150°C (302°F). The procedure to activate this mechanism is as follows: 1) Parts are bonded and clamped at room temperature for four hours. 2) The clamped parts are then heated at 150°C (302°F) for two hours. 3) After the two hours, the bond will be thermally resistant up to 250°C (482°). Features & Benefits: Rapid development of high strength Ease of use – no mixing or heat cure Bonds most materials 100% reactive, no solvents Information provided by Permabond.
