3M™ 427 Aluminum Foil Tape 3" x 60 Yds. 4.6 Mil Silver

Description

3M™ aluminum foil tape 427 is the go-to foil tape for numerous applications across a broad range of industries. Comprised of a dead soft aluminum foil backing with a highly engineered pressure sensitive acrylic adhesive it is ideal for heat shielding and de-paint operations.

Withstands exposure to high heat and humidity consisting of a dead soft thermally conductive aluminum backing 3M™ aluminum foil tape 427 dissipates heat over the surface of the tape to reduce hot spots and protect the substrate from the effects of high temperatures. It is a linered version of our 3M™ aluminum foil tape 425 making it suitable for die cutting applications. Coated with our highly engineered acrylic adhesive it is capable of withstanding exposure to high heat and humidity while maintaining a strong and reliable bond. This tape can withstand a variety of moisture weathering UV and solvents in order to provide an excellent work life indoors or out.
