Fast-Setting Flexible Black MMA Adhesive for Bonding Metal, Plastic, and Composites

Infinity Bond MMA Black Adhesive for Quick, Flexible Bonding Applications

Infinity Bond MMA 420 Black is a fast-setting structural adhesive designed for bonding metals, plastics, and composites with flexibility and speed. With a 3 to 7 minute working time and a 10:1 mix ratio, this adhesive is perfect for rapid assembly lines or applications where quick turnaround is critical. It bonds strongly to stainless steel, aluminum, fiberglass, and ABS with minimal surface prep. The black pigmentation improves visibility for inspection, alignment, and aesthetic consistency during production.
