Use the versatile 3M™ Aluminum Foil Tape 427 for a multitude of indoor and outdoor applications such as general purpose holding, patching, sealing and much more. Our tape is dead soft, aluminium foil backed with a pressure sensitive acrylic adhesive. it is ideal for heat shielding, heat reflecting, chemical masking, light enhancement, chemical milling, seaming, sealing 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.
