3M™ Aluminum Foil Tape 425 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 serves has excellent heat and light reflection to protect against high temperature and U.V. 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 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.
