Designed for Difficult-to-Bond, Low Surface Energy Rubbers 3M™ Scotch-Weld™ Instant Adhesive Primer AC79 is designed for difficult-to-bond, low surface energy elastomers. This primer (PDF, 239 Kb) should be applied to each low surface energy substrate surface to achieve desired results.
Recommended Applications Improves adhesion of cyanoacrylate adhesives to:
Difficult-to-bond flexible elastomers
EPDM
Silicone
Fluoroelastomers
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 hold 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.
