3M 7010370735 Double Coated Tape 3 7/8 in 144 Yd

Product Description

The 3M 7010370735 is a double coated tape built on a 1 mil clear PET carrier with two distinct adhesive systems: 3M Adhesive 350 acrylic on the face side and a 3 mil silicone adhesive on the liner side. This dual-adhesive construction allows technicians to bond silicone rubber elastomers, silicone foam, and silicone gasketing materials to a wide range of substrates in a single application. The acrylic adhesive delivers strong temperature and chemical resistance, while the silicone adhesive side provides reliable adhesion to silicone-based surfaces. It ships in roll form at 3 7/8 inches wide and 144 yards long.

This tape is suited for demanding industrial and mechanical assembly applications where standard adhesive tapes fail due to silicone substrate incompatibility. Typical use cases include mounting silicone gaskets, bonding silicone foam seals, and securing silicone rubber components to metal, plastic, or composite surfaces. The double liner format — Adhesive 350 on a 58 4.2 mil PCK liner and silicone adhesive on a 3 mil PET liner — gives assemblers control over which adhesive side is exposed during layup. It is commonly used in HVAC gasket fabrication, electronics assembly, and industrial sealing applications.

Key Features

• Dual-adhesive system: 3M Adhesive 350 acrylic on face side, 3 mil silicone adhesive on liner side
• 1 mil clear PET carrier provides dimensional stability and transparency
• Acrylic adhesive side offers high temperature and chemical resistance
• Silicone adhesive side bonds reliably to silicone rubber and foam substrates
• Double linered construction for controlled, sequential liner removal during assembly
• Roll format — 3 7/8 inches wide by 144 yards long — suitable for high-volume or continuous bonding work

Compatibility

Designed for bonding silicone rubber elastomers, silicone foam, and silicone gasketing materials to a broad range of substrates including metals, plastics, and composites in industrial and HVAC assembly applications.

Installation Notes

Surface preparation is critical before applying double coated tape — clean and dry all bonding surfaces thoroughly to remove oils, dust, and contaminants. Apply firm, even pressure across the full bond area after positioning to ensure full adhesive contact. Remove the appropriate liner last based on which adhesive side contacts the silicone substrate. Follow all applicable safety data sheet guidance when working with adhesive tapes in confined or high-temperature environments.
