Information
The 3M?Foil Tape?431 (75?mm width) is the premium format for applications requiring broad substrate coverage with the same high performance in heat reflection, moisture/UV resistance and conformability. Aerospace MRO engineers may use this width to quickly cover non?structural damage or to protect large panels temporarily during high?temperature processing, surface preparation or in service repair operations. The foil backing serves as a thermal barrier and sealed adhesive layer, helping prolong component life by reducing exposed area to environmental stressors. Its acrylic adhesive ensures long?term bonding, and the product meets aerospace flame?propagation criteria making it a trusted choice for non?structural protective sealing.
