3M 7100039243 Scotch-weld SI1500 Instant Adhesive Clear 1 Lb

Product Description

The 3M 7100039243 is a high-viscosity, surface-insensitive instant adhesive sold under the Scotch-Weld SI1500 product line. It is formulated to bond quickly to substrates that standard cyanoacrylate adhesives struggle with, including rough, porous, contaminated, and acidic surfaces. The clear finish makes it suitable for visible joint lines where aesthetics matter. This adhesive is used by contractors, fabricators, and maintenance professionals working with wood, cardboard, veneer, fabric, cork, and leather in light industrial and commercial applications.

SI1500 is well suited for assembly and repair operations where substrate conditions cannot be controlled or cleaned prior to bonding. Typical applications include woodworking shops, upholstery and leather fabrication, packaging assembly, and general maintenance tasks where fast fixture time is required on difficult-to-bond materials. The 1-pound unit size is appropriate for production-scale or repeat-use tasks rather than single-use repair.

Installation Notes

This adhesive is applied by trained assembly or maintenance personnel and does not require power-down procedures. Work in a well-ventilated area and follow standard cyanoacrylate handling precautions, including avoiding skin and eye contact. Surfaces should be free of loose debris where practical, though the SI1500 formulation tolerates contamination better than standard instant adhesives. Cap the container immediately after use to prevent moisture-induced cure.
