• FM® 73 Adhesives Film
FM® 73 film adhesive is a toughened, general purpose aerospace epoxy designed to provide excellent structural performance from -67ºF to 180ºF (-55C to 82°C). FM® 73 film adhesive is formulated to provide outstanding durability in bonding metals and is also suitable for bonding many structural composite systems.

Extensive testing has proven that FM® 73 meets stringent environmental resistance and bonding durability requirements. To achieve maximum environmental resistance and bonding durability the use of BR® 127 corrosion inhibiting primer is recommended in bonding metallic components.

Applications for FM® 73 include metal-to-metal bonding, composite-to-composite bonding, and composite-to-metal bonding.
