3M 7000000894 Scotch-weld Instant Adhesive CA40 1 Pound

Product Description

The 3M 7000000894 Scotch-Weld Instant Adhesive CA40 is a low-viscosity, fast-setting cyanoacrylate adhesive formulated for bonding rubbers and elastomers. CA40 achieves rapid cure without mixing and delivers reliable adhesion to difficult-to-bond substrates including EPDM rubber, aluminum, and flexible vinyls. It also bonds to most cured rubbers and plastics, making it a versatile choice for repair, fabrication, and assembly tasks across trade and industrial environments. Sold in a 1-pound package, this adhesive is suited for higher-volume applications where consistent bond strength to rubber and plastic substrates is required.

CA40 is appropriate for use in HVAC, plumbing, pool, and general mechanical service applications where rubber gaskets, elastomeric seals, or flexible components need fast, reliable bonding. It performs well in both shop and field settings. Licensed technicians and service professionals use CA40 when standard mechanical fasteners or slower-cure adhesives are not practical for the substrate or repair scenario.

Key Features

• Low viscosity formula flows into tight joints and irregular surfaces on rubber and elastomeric parts
• Fast-setting cure requires no mixing and minimal fixturing time
• Bonds EPDM rubber, aluminum, flexible vinyls, cured rubbers, and most plastics
• 1-pound package supports high-frequency or higher-volume bonding tasks
• Suitable for repair and assembly in trade service environments

Compatibility

Designed for bonding rubbers, elastomers, EPDM rubber, aluminum, flexible vinyls, cured rubbers, and most plastics. Verify substrate compatibility and surface preparation requirements before application.

Installation Notes

Surface preparation is critical for cyanoacrylate adhesives — clean and dry all bonding surfaces before application to achieve full bond strength. Apply adhesive sparingly, as excess material can inhibit cure or cause unwanted bonding. Avoid skin contact and use in a well-ventilated area in accordance with the product safety data sheet. Cyanoacrylate adhesives bond rapidly on contact, so part alignment must be confirmed before joining surfaces.
