3M™ aluminum foil tape 431 is designed for numerous applications across a broad range of industries. This tape is comprised of a dead soft aluminium foil backing and coated with a highly engineered pressure sensitive acrylic adhesive.
- Heat and light reflective tape protects surfaces and enhances lighting efficiency
- Thermally conductive tape reflects and dissipates radiant heat to protect plastic surfaces
- Robust acrylic adhesive and foil backing provides long service life, both indoors and out
- Withstands exposure to flame, weathering, moisture, and UV for a strong, long-lasting, and reliable bond
- Clean removal after harsh masking applications
- Conforms to curved and uneven surfaces
- Tensile strength: 85 [Newton/25 mm]
- Aluminum foil back material
Use lightweight 3M™ aluminum foil tape 431 for aerospace, appliance and automotive sealing, splicing, holding, or masking applications. It also makes a good maskant in electroplating of aluminium because it will not contaminate the bath. Due to the low moisture vapour transmission rate, this tape offers excellent sealing and patching performance.
Recommended applications include creative/decorative applications, moisture and vapour barrier, general-purpose heat reflector and heat dissipater, mechanically hold wires and cooling coils in 'white goods' appliances, repairs tears on truck trailers and aircraft, splicing of thin gauge foils, general-purpose holding, and patching and sealing applications.
