3M™ Scotch-Weld™ instant Adhesive CA40 is a high-strength, very fast-setting cyanoacrylate adhesive that cures at room temperature with very low bonding pressures. It has particularly good adhesion to many difficult to bond substrates such as EPDM rubber, aluminum and flexible vinyl.
Instant, High Strength Results
3M™ Scotch-Weld™ Instant Adhesive CA40 is a high strength cyanoacrylate instant adhesive. This low viscosity liquid adhesive bonds in only seconds (3 to 20 seconds) while still allowing a brief amount of time for alignment of parts. Once bonded, the adhesive will fully cure in just 24 hours. It can withstand a wide range of temperatures from- 65°F/-54°C to 180°F/82°C. This adhesive will bond to an extremely wide selection of materials and is useful in applications in most industries.
What are Cyanoacrylate Adhesives?
Cyanoacrylate adhesives (instant adhesives) are single component, lower viscosity liquids that cure extremely quickly with just contact pressure and surface moisture. They adhere well, with thin bond lines, to plastics, metals and rubbers. With the use of primers, they can also adhere to low surface energy plastics and elastomers. They have lower flexibility, peel strength and impact resistance compared to other structural adhesives. They are generally used for gasket bonding and smaller assemblies.
