Solvay FM® 73M Epoxy Film Adhesive
Categories:	Polymer; Adhesive; Thermoset; Epoxy; Epoxy Adhesive
Material Notes:	Description: FM® 73 film adhesive is a toughened, general purpose aerospace epoxy designed to provide excellent structural performance from -67°F to 180°F (-55°C to 82°C). FM 73 film adhesive is formulated to provide outstanding durability in bonding metals and is also suitable for boding many structural composite systems. Extensive testing has proven that FM 73 adhesive 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. Features & Benefits: Demonstrates excellent peel strength and structural performance from -67°F to 180°F (-55°C to 82°C) Resistant to pre-bond humidity exposure Good moisture and corrosion resistance in high humidity Shop life of 15 days at 75°F (24°C) Applications: Metal-to-metal bonding Composite-to-composite bonding Composite-to-metal bonding Information provided by Cytec, subsequently acquired by Solvay.
