Pinch for a Precise Drop or Squeeze for a Steady Bead
Our 3M™ Scotch-Weld™ Instant Adhesive CA40H is a glue that is easily applied with a thin bond line from a squeeze bottle and cures quickly. This cyanoacrylate adhesive is dispensed from a flexible container; pinch a precise drop or squeeze for a steady bead. It offers better void filling capabilities than many other lower viscosity instant adhesives.
Recommended Applications
- Gasket attachment
- Small joint assembly
- Jewelry assembly
- Orthopedics and footwear
Creates a Strong, Durable, Long-Lasting Bond
Once applied, our 3M™ Scotch-Weld™ Instant Adhesive CA40H typically reaches handling strength in under 40 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 2,000 psi.
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.
