Infinity Bond MMA 422 Black Adhesive for Flexible Bonding with Extended Working Time
Infinity Bond MMA 422 Black is a flexible methacrylate adhesive designed for bonding metal, plastic, and composite materials with an extended working time. With an 18 to 24 minute working time and 10:1 mix ratio, it’s ideal for complex assemblies, large components, or warmer shop environments. It delivers high-strength, impact-resistant bonds to substrates like fiberglass, ABS, aluminum, and stainless steel — all with minimal prep.
