The foil also serves as an excellent barrier against moisture, dust, flame, and certain chemicals as used in aircraft paint stripping masking and the tape is also a good candidate as a maskant in electroplating of aluminum because it will not contaminate the bath. Its very low moisture vapor transmission rate also makes the tape a good sealant.

Our special acrylic adhesive supplies superior temperature, U.V. and solvent resistance to produce a strong, lasting and reliable bond. It provides excellent age life and is ideal for harsh, long-term indoor and outdoor environments.

3M™ Aluminum Foil Tape 425 meets U.L. 746C (File E 122798) and 723, Class "L" for low flammability rating (File R 7311). It can be certified to meet SAE-AMS-T-23397 and LT-80C and meets F.A.R 25.853(a), O447 Temperature use range is from -65° to 300°F (-54° to 149°C).
