Overview
3M™ Aluminum Foil Tape 425 is designed for demanding aerospace and industrial applications requiring heat reflection, chemical resistance, and moisture sealing. Its dead soft aluminum foil backing conforms to curved surfaces, while the acrylic adhesive provides strong adhesion and clean removal after harsh masking operations. This tape withstands temperatures from -65°F to 300°F (-54°C to 149°C), resists flame, weathering, UV, and chemicals, and enhances lighting efficiency through its reflective surface. Common uses include heat shielding, chemical milling, de-paint masking, seaming, sealing, and coil attachment in refrigeration systems.
