FM365 is suitable for general gap filling, bonding and insulation applications. These include the perimeter sealing and fixing of windows and doors, sealing of non-fire rated service penetrations and sealing around insulation panels. FM365 is not UV resistant and should be protected from sunlight with a suitable opaque sealant, filler or paint. As with all PU foams, it does not bond to polythene, polypropylene, Teflon®, siliconized or wax- like surfaces. Safety data sheet must be read and understood before use. Extremely flammable - keep away from open flames and other ignition sources.
