Superior Heat Management: The thermally conductive aluminum backing efficiently dissipates heat across the surface, reducing hot spots and protecting sensitive materials. It is ideal for applications requiring enhanced heating or cooling efficiency.

Chemical and Environmental Resistance: Resistant to a wide range of chemicals, solvents, and exposure conditions, this tape protects surfaces during de-painting and other chemical masking processes. It maintains its integrity even under harsh environments, such as high heat (up to 300°F/149°C), humidity, and UV exposure.

Easy Clean Removal: The advanced acrylic adhesive delivers a strong, durable bond while allowing for clean removal after intense masking applications, making it perfect for temporary surface protection.

Versatile Applications: 3M™ Aluminum Foil Tape 425 is suitable for various applications, including heat shielding, light reflection for enhanced lighting efficiency, chemical milling, moisture barriers, and sealing and splicing tasks.

Heat shielding and reflecting for temperature-sensitive materials

Masking during chemical paint stripping processes

Light reflecting for enhanced illumination

Moisture and vapor barrier

Chemical milling operations

Seaming, sealing, and splicing of thin gauge foils

Refrigeration and freezer coil attachment

Protective covering for plastics

Flame and Weather Resistant: Designed to withstand exposure to flame, weathering, moisture, and UV, this tape ensures long-lasting performance indoors or outdoors.

Highly Conformable: The dead-soft aluminum foil backing easily conforms to irregular and uneven surfaces, providing a reliable seal even on complex shapes.

Industry Recognized: Certified for low flammability with UL 746C and UL 723 Class “L” classifications, and meets L-T-80C and F.A.R 25.853(a) standards, ensuring safety and compliance in critical applications.
