Usage/purpose

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.
