Product Description
3M Aluminum Foil Tape 425 sets a dead soft aluminium foil backing under a clear acrylic adhesive. The foil throws back both heat and light, and moisture vapour barely passes through it, so the tape doubles as a serviceable seal. It carries UL 723 Class L low flammability, FAR 25.853(a) and L-T-80C, and stays put indoors or out over long service.
