3M 7000049099 Double Coated Tape 0.25 in 36 Yd Roll

Product Description

The 3M 7000049099 is a double coated tape built on a 1 mil clear PET carrier with a high-performance acrylic adhesive on the face side and a silicone adhesive on the liner side. This dual-adhesive construction targets demanding bonding applications where one substrate is a silicone-based material. The tape is 0.25 inches wide and supplied in a 36-yard roll. It is used by industrial maintenance technicians, fabricators, and trade professionals who need reliable adhesion between silicone components and dissimilar substrates without mechanical fasteners or liquid adhesives.

This tape is suited for applications involving silicone rubber elastomers, silicone foam, and silicone gasketing materials bonded to metal, plastic, or other substrates. It performs well in environments requiring strong temperature resistance and chemical resistance, making it appropriate for HVAC gasketing, electrical enclosure sealing, and similar trade applications where silicone-to-substrate bonds must hold under thermal cycling or exposure to chemicals.

Key Features

• 1 mil clear PET carrier provides dimensional stability and transparency
• Face side uses 3M Adhesive 350 acrylic adhesive for exceptional temperature and chemical resistance
• Liner side uses a 3 mil silicone adhesive that bonds reliably to silicone substrates
• Double linered construction: Adhesive 350 on a 4.2 mil PCK liner and silicone adhesive on a 3 mil PET liner
• Ideal for attaching silicone rubber elastomers, silicone foam, and silicone gasketing
• Transparent carrier keeps bond area visually clean in finished assemblies

Compatibility

Designed for bonding silicone rubber elastomers, silicone foam, and silicone gasketing materials to a range of substrates including metals and plastics in demanding industrial and trade applications.

Installation Notes

Surface preparation is critical before applying double coated tape; clean and dry both substrates thoroughly to remove oils, dust, and contaminants. Apply firm, even pressure across the full bond area to ensure full contact between adhesive and substrate. Do not stretch the tape during application, as this can reduce bond strength. This tape is applied by hand and requires no special tools, but a roller or squeegee improves adhesive contact on flat surfaces.
