Our 3M aluminum foil tape 437 features a dead soft aluminum foil backing with an acrylic pressure sensitive adhesive on a polycoated kraft paper liner. It utilizes a high tack adhesive that meets automotive OEM requirements and allows for quick and easy application on assembly lines. Consisting of a dead-soft, thermally conductive aluminum backing, 3M aluminum foil tape 437 dissipates heat over the surface of the tape to reduce hot spots and protect the substrate from the effects of high temperatures. Coated with our highly engineered, aggressive acrylic adhesive, it is capable of withstanding exposure to high heat (up to 212 deg F/100 deg C) and humidity while maintaining a strong and reliable bond, even to low surface energy substrates. This tape can withstand a variety of moisture, weathering, UV and solvents in order to provide an excellent work-life, indoors or out.
- Durable aluminum foil backing offers ideal properties for long serviceable life indoors and out
- Thermally conductive and reflective backing assists with heat shielding
- Pressure sensitive acrylic adhesive meets automotive OEM requirements
