Black MMA Adhesive for Long Working Time Applications
Infinity Bond MMA 330 Black is a long-working-time methacrylate adhesive designed for structural bonding of metal, plastic, and composite materials. With an 18 to 32 minute working time and 1:1 mix ratio, it’s ideal for bonding large assemblies, adjusting complex parts, or working in warmer conditions where slower set times are preferred. It bonds well to fiberglass, ABS, aluminum, and stainless steel with minimal surface preparation. The black color provides visual contrast for alignment, inspection, or cosmetic consistency in production workflows.
Note: There is also an MMA 330 cream/off-white option for standard bonding applications.
