MMA 422 Black Structural Adhesive for Flexible, Extended Working Time Applications
Infinity Bond MMA 422 Black is a flexible, long-working-time structural adhesive designed for bonding metals, plastics, and composites in demanding applications. With an 18 to 24 minute working time and a 10:1 mix ratio, it’s ideal for large parts, complex setups, or warmer environments where extended working time is critical. It forms high-strength, flexible bonds to stainless steel, aluminum, fiberglass, ABS, and more — all with minimal surface prep.
