Solvay BR® 680-3 Polyimide Film Adhesive
Categories:	Polymer; Adhesive
Material Notes:	Description: BR® 680-3 paste adhesive is a radar transparent, viscous/thixotropic material supplied at 60 – 65% solids. It is intended for bonding both metallic and non-metallic sandwich structures. It is equally suitable for bonding metals and composite laminates.BR 680-3 is co-curable at temperatures up to 700°F (371°C) with various polyimide composites. Although not mandatory, BR® 680 adhesive primer may be used to seal prepared metal surfaces. Features & Benefits: 700°F (371°C) service temperature Developed specifically for honeycomb sandwich bonding 350°F (177°C) processing Radar transparent Superior thermal oxidative stability Co-curable with Avimid N and other poyimide composite materials Condensation-type polyimide Applications: Honeycomb sandwich construction Metal-to-metal bonding Composite-to-metal bonding Composite-to-composite bonding Information provided by Cytec, subsequently acquired by Solvay.
