Technical Information
3M 425 is a 4.6 mil dead-soft aluminum foil tape with an aggressive acrylic adhesive system that conforms easily to irregular duct surfaces and provides a durable, airtight, moisture-resistant seal on HVAC ductwork, refrigeration insulation, and thermal jacketing. The dead-soft aluminum foil backing allows hand conforming to contoured surfaces without springing back, while the acrylic adhesive maintains bond integrity across a wide temperature range. 3M 425 is also widely used for EMI/RFI shielding applications, reflecting radiant heat in thermal insulation systems, and sealing metal flashing and foil-faced insulation joints in building construction.
Why Choose 3M 425 Aluminum Foil Tape?
- Dead-Soft Aluminum Foil — Conforms easily to curved and irregular duct surfaces without springing back
- Airtight HVAC Sealing — Creates moisture-resistant, airtight seal on ductwork and insulation
- 4.6 Mil Thickness — Durable foil construction for long-term HVAC and industrial use
- Acrylic Adhesive — Temperature-resistant adhesive maintains bond across service range
- EMI Shielding Capable — Conductive aluminum foil provides electromagnetic shielding function
