3M™ Scotch-Weld™ Surface Insensitive Instant Adhesive SI Gel is a gel viscosity instant adhesive. The SI Gel instant adhesive is formulated to give exceptional performance on wood, leather and paper. Once applied, the glue has fast handling time and cure to keep jobs moving quickly.
Creates a Strong, Durable, Long-Lasting Bond
Once applied, our 3M™ Scotch-Weld™ Surface Insensitive SI100 typically reaches handling strength in under 25 seconds, with a full cure achieved in 24 hours. This keeps jobs moving quickly and may help improve workplace productivity. Once a full cure is achieved, the glue achieves a strong, durable and lasting bond, with overlap shear strength over 2,000psi.
Surface Insensitive Instant Adhesives
Our 3M™ Scotch-Weld™ Surface Insensitive Instant Adhesives are designed to give exceptional performance on difficult-to-bond wood, leather, paper and other acidic substrates. These adhesives can bond like substrates or in combination with metal, plastics, rubbers or composite substrates.
Understanding Instant Adhesives
Instant adhesives are cyanoacrylate based formulas that are strong, fast-acting glues used in industrial and household applications. In general, they are an acrylic resin that rapidly polymerizes in the presence of moisture, forming long, strong chains, joining the bonded surfaces together.
Cyanoacrylate adhesives should be applied thinly, with pressure put on the bond for a few seconds, to ensure that the reaction proceeds rapidly and a strong bond is formed within a reasonable time.
3M instant adhesives apply right from the container and rapidly reach handling strength at room temperature. Commonly referred to as a super glue, a single drop per square inch can bond many plastics, rubbers, metals, wood and more. An instant adhesive from 3M set a Guinness World Record in 2012 for the strongest glue by lifting an 8.1 metric ton forklift in the air for one hour.
