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.
