Structural Adhesive with Extended Working Time

Infinity Bond MMA 330 Black is a long-working-time structural methacrylate adhesive designed for bonding metals, plastics, and composites with precision and strength. With an 18 to 32 minute working time and a 1:1 mix ratio, this adhesive is ideal for large assemblies or applications requiring extended setup time. It forms strong, durable bonds to substrates like aluminum, stainless steel, fiberglass, and ABS — all with minimal surface preparation. The black color provides clear visual contrast for inspection, alignment, or aesthetic blending in production environments.

Note: There is also an MMA 330 off-white option for standard bonding applications.
