3M CA40H High Viscosity Cyanoacrylate For Aluminum / EPDM Industrial Bonding

3M CA40H High-Viscosity Cyanoacrylate for Aluminum/EPDM Industrial Bonding

Basic Properties​

3M CA40H is a single-component cyanoacrylate adhesive with 400-600 cP viscosity (higher than CA40) and 5-40 sec cure time. Designed for bonding challenging substrates like aluminum, EPDM rubber, and flexible vinyl, with resistance to soap solutions and isopropyl alcohol.

Product Description​

CA40H prevents run-off on vertical surfaces and allows extended alignment time (1.5x slower than CA40). With a -54°C to 100°C temperature range, it bonds metals to elastomers in automotive, electronics, and industrial repair.

Characteristics​

Application Scenarios​

Automotive Seal Repair: Bonds cracked EPDM door seals, sets in 40 sec, withstands -30°C impact (Ford Repair Manual case), 50% faster than epoxy.
Conveyor Belt Repair: Mends EPDM joints in mining belts. Resists coal dust/moisture (>15 MPa), extends lifespan by 2 years.
Outdoor Sealing: Bonds aluminum housings to EPDM gaskets. Achieves IP67 rating (1m/30min immersion), implemented in 5G base stations.
