3M 425 Aluminum Foil Tape

aluminum foil tape 425

3M Aluminum Foil Tape 425 is a 2.8 mil dead-soft aluminum foil backing combined with a special transparent synthetic acrylic adhesive that makes this our best general purpose foil product available. This tape has excellent heat and light reflection to protect against high temperatures and U.V. degradation.

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.

The 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).
