3M 7100039258 Si Gel Instant Adhesive Clear 20g

Product Description

The 3M 7100039258 is a high-viscosity, gap-filling instant adhesive formulated for surface-insensitive bonding in demanding trade and industrial applications. The SI Gel formula handles rough, porous, contaminated, and acidic substrates where standard cyanoacrylate adhesives typically fail or cure unpredictably. Each unit ships as a 20-gram clear gel. Licensed technicians, maintenance professionals, and skilled tradespeople working across HVAC, plumbing, electrical, and facilities maintenance applications rely on this product for fast, reliable bonds on difficult materials without surface prep.

This adhesive is suited for bonding wood, cardboard, veneer, fabric, cork, and leather in both residential and commercial maintenance and installation environments. The gel consistency allows for controlled application on vertical surfaces and into gaps, making it practical in tight service locations where a low-viscosity liquid adhesive would run. It is also effective for field repairs where substrate cleanliness cannot be guaranteed.

Key Features

• Surface-insensitive formula bonds rough, porous, contaminated, and acidic substrates
• High-viscosity gel consistency prevents runoff on vertical or overhead surfaces
• Gap-filling capability accommodates uneven or irregular mating surfaces
• Clear cure color maintains appearance on visible or finished surfaces
• 20-gram package suitable for single-use or small-batch field applications

Compatibility

Designed for bonding wood, cardboard, veneer, fabric, cork, and leather substrates. Performs on surfaces that are rough, porous, contaminated, or acidic where standard instant adhesives are not recommended.

Installation Notes

Applied by hand using standard adhesive dispensing technique — no special tools required. Ensure container is sealed immediately after use to prevent premature cure. Keep away from skin contact during application; standard chemical-resistant gloves are recommended. Store according to manufacturer guidelines to maintain shelf life.
