FM® 680-1 polyimide adhesive is a non-metallic version of FM 680 film adhesive designed for continuous service at temperature up to 700°F (371°C). FM 680-1 adhesive was specifically developed for radar transparent applications requiring extreme environmental durability. FM 680-1 adhesive is capable of bonding composite laminates and a wide variety of high temperature metallic substrates such as stainless steel and titanium while maintaining thermal oxidative stability. FM 680-1 adhesive is an excellent candidate for aircraft engine applications or for the bonding of new composite materials requiring co-cure or consolidation temperature up to 735°F (391°C). This adhesive is processible under standard manufacturing operations at temperatures as low as 600°F (316°C) and can handle freestanding post-cure up to 735°F (391°C). To achieve maximum performance in bonding prepared metallic details the use of BR® 680 primer is recommended. FM 680-1 adhesive is a non-aluminum-filled, condensation polyimide supported on fiberglass cloth. It is available in film, foam and paste forms. FM 680-1 adhesive utilizes the NR-150 B2 chemistry developed by DuPont. Suggested Applications: Titanium bonding Stainless steel bonding Polyimide composite bonding&& |
