Industrial-grade aluminum foil tape with thermally conductive backing for heat shielding, chemical masking, and temperature protection up to 300°F. UL certified, 16 rolls per case.
3M™ Aluminum Foil Tape 425 is a premium industrial-grade foil tape designed for demanding applications across aerospace, automotive, appliance, and general industrial sectors. This versatile tape features a dead soft aluminum foil backing combined with a highly engineered pressure-sensitive acrylic adhesive, making it ideal for heat shielding, heat reflecting, chemical masking, light enhancement, chemical milling, seaming, sealing, and de-paint operations. The thermally conductive aluminum backing effectively dissipates heat over the tape surface to reduce hot spots and protect substrates from high temperature effects, while maintaining a strong and reliable bond even in extreme conditions.
The tape withstands exposure to high heat up to 300°F (149°C) and operates reliably across a temperature range from -65°F to 300°F (-54°C to 149°C). Its engineered acrylic adhesive provides exceptional durability while maintaining the ability to remove cleanly after harsh masking applications, making it suitable for both temporary and permanent installations. The tape resists chemicals, moisture, weathering, and UV exposure, ensuring excellent work life both indoors and outdoors. With a total thickness of 4.6 mil and a backing thickness of 2.8 mil, this single-sided adhesive tape delivers consistent performance across diverse substrates.
This product is UL Recognized to UL 746C (File E 122798) and Classified by UL to UL 723 Class 'L' for low flammability rating (File R 7311), meeting FAR 25.853(a) and L-T-80C specifications. Each case contains 16 rolls, with each roll measuring 1.5 inches wide by 60 yards long, providing 960 linear yards of coverage per case. The 24-month shelf life ensures long-term storage capability for inventory management.
