3M 425 Aluminum Foil Tape is a dead-soft aluminum foil-backed tape with a special transparent synthetic acrylic adhesive, making this the best general-purpose foil product available. This tape is ideal for masking, sealing, seaming, shielding, chemical stripping, harness wrapping, joining, electroplating, plastic protection, chemical milling, heat shielding, heat reflecting and paint stripping.
✓
3M Aluminum Foil Tape 425 has excellent heat and light reflection to protect against high temperature and ultraviolet (UV) degradation. It's also an effective barrier against moisture, dust, flame, dirt and mild chemicals used in paint stripping and masking.
✓
The thermally conductive backing of 3M 425 helps maximize efficiency by dissipating heat over a wider surface area. The synthetic acrylic adhesive provides 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.
✓
Uses and applications include aircraft paint stripping masking (approved by the Department of the Navy Technical Order TO 1-1-8), moisture barrier in "white goods" appliances, general-purpose heat reflector and heat dissipator, mechanically holds wires and cooling coils in "white goods" appliances, and more. Carrier/Backing: aluminum foil. Adhesive: synthetic acrylic. Thickness: 4.6 mils (carrier, adhesive) 2.8 mils (carrier).
✓
Adhesion: 47 ounces per inch (to stainless steel test panel). Tensile Strength: 30 pounds per inch (longitudinal). Service/Operating Temperature: -65F to 300F. Elongation: 8%. Standards Met: meets U.L. 746C (File E 122798) and 723, Class "L" for low flammability rating (File R 7311); can meet SAE-AMS-T-23397 and L-T-80C; meets F.A.R 25.853(a), O447.
