Infinity Bond MMA 422 Off-White Adhesive for Flexible, Long Working Time Applications
Infinity Bond MMA 422 is a flexible methacrylate adhesive designed for bonding metal, plastic, and composite materials with extended working time. With an 18 to 24 minute working time and 10:1 mix ratio, it’s ideal for large assemblies, precise part alignment, or temperature-sensitive applications. It bonds strongly to fiberglass, ABS, aluminum, and stainless steel with minimal surface prep. The off-white formula is suitable for applications where visual contrast is not required or where a more neutral bond line is preferred.
Note: MMA 422 is also offered in black for environments where visual contrast is preferred.
