Hi Temp Resistant B-Staged Adhesive Film from Master Bond
Flexible bonding film can be cut to various shapes.
Hackensack, NJ — Master Bond has developed FLM36 for bonding and sealing applications in the aerospace, electronic, opto-electronic and specialty OEM industries. This B-staged film eliminates mixing and measuring and is reportedly easy to handle. FLM36 is a B-staged film with a flexibilized epoxy chemistry that offers high temperature resistance, thermal conductivity, electrical insulation and the ability to withstand rigorous thermal cycling. The film can withstand temperatures up to 500°F (260°C) and retains its high strength properties upon prolonged exposure to elevated temperatures. It bonds well to a variety of substrates including metals, composites, glass and many plastics. In addition, the thermally conductive material is also a superior electrical insulator.

Unlike other heat-resistant epoxy systems, FLM36 possesses more flexibility and toughness, which enables it to endure thermal and mechanical shocks as well as thermal cycling. It also has good chemical resistance to water, acids, bases, fuels and oils. The film has release paper on each side. After the substrates to be bonded are properly prepared, the release paper is removed to expose the adhesive. It's carefully placed onto the part and pressure is applied. The assembly is lightly fixtured and cured for 1-2 hours at 350°F (177°C). The bonded parts should be returned to 75°F (25°C) before removing the fixtures. The material offers uniform bond line thickness and limited squeeze out during bonding. This product is offered in three standard sizes: FLM36-4A is 4 x 4 x 0.008-in. (101.6 x 101.6 x 0.2mm), FLM36-8B is 8 x 8 x 0.008-in. (203 x 203 x 0.2mm) and FLM36-12C is 12 x 12 x 0.006-in. (305 x 305 x 0.15mm).

The film can be cut with a pair of sharp scissors into various shapes and sizes. The films are rugged, durable and not prone to cracking. Contrary to most thermoset films of this type, FLM36 does not require freezing or refrigeration.
