3M 7100115007 Double Coated Tape 6 in 36 Yd 5.5 Mil

Product Description

The 3M 7100115007 is a double coated tape built on a 1 mil clear PET carrier with two distinct adhesive systems: 3M Adhesive 350 acrylic adhesive on the face side and a 3 mil silicone adhesive on the liner side. Total tape thickness is 5.5 mil. This construction is engineered specifically for demanding bonding applications where standard acrylic-only tapes fall short. The tape ships in a 6 inch wide by 36 yard roll. Licensed HVAC, industrial maintenance, and mechanical technicians regularly specify this product when bonding silicone-based materials to dissimilar substrates in high-temperature or chemically aggressive environments.

This tape is suited for applications requiring a durable bond between silicone rubber elastomers, silicone foam, and silicone gasketing to a range of substrates. Typical use cases include silicone gasket attachment, sealing assemblies, and component lamination in environments where chemical resistance and elevated operating temperatures are factors. The dual-adhesive design addresses the challenge of bonding silicone surfaces, which resist adhesion from most standard acrylic tapes. It is available in roll form and is handled with standard tape application tools and cutting equipment.

Key Features

• Dual adhesive system: 3M Adhesive 350 acrylic on face side for temperature and chemical resistance
• 3 mil silicone adhesive on liner side bonds reliably to silicone substrates
• 1 mil clear PET carrier provides dimensional stability and transparency
• Double-linered construction: 4.2 mil PCK liner on face side, 3 mil PET liner on silicone side
• Ideal for bonding silicone rubber elastomers, silicone foam, and silicone gasketing
• Total tape caliper of 5.5 mil suits thin-bond-line assembly requirements

Compatibility

Designed for bonding silicone rubber elastomers and silicone foam to a range of substrates, with particular suitability for silicone gasketing applications where standard adhesive tapes lack adequate adhesion to silicone surfaces.

Installation Notes

Surface preparation is critical before application — clean and dry all bonding surfaces to remove oils, dust, and contaminants. Apply firm, uniform pressure across the tape surface after placement to ensure full adhesive contact. Remove liners in the sequence appropriate to the assembly process, keeping the silicone-adhesive liner in place until the part is positioned against the silicone substrate. Follow applicable facility or code guidelines for adhesive use in enclosed or high-temperature spaces.
