L-310FR ADHESIVE  is a flame-retardant, modified phenolic film adhesive that improves the peel strength of phenolic prepreg when bonded to honeycomb core materials. Designed for vacuum or platen press cure cycles, the adhesive film is placed directly between the core and uncured prepreg face ply. L-310FR is intended to be co-cured with the phenolic prepreg during the normal prepreg cure cycle.

Features and Benefits
• A single layer of L-310FR adhesive film can increase the peel strength of a phenolic honeycomb bond by up to 5x with no significant increase in flammability or smoke emission
• L-310FR can also be used to bond cured face sheets to honeycomb core
• L-310FR can also be used for bonding decorative laminates to B and C-staged phenolic composite laminates
• L-310FR film adhesive is very stable at room temperature
• Meets or exceeds the flammability requirements of FAR Part 25.853
• Film is blue in color
