Infinity Bond MMA 422 Black Flexible Methacrylate Adhesive – Long Working Time

Infinity Bond MMA 422 Black Structural Adhesive for Long-Working-Time Applications

Infinity Bond MMA 422 Black is a flexible structural adhesive engineered for bonding metals, plastics, and composites in applications requiring extended working time. With an 18 to 24 minute working time and 10:1 mix ratio, it’s ideal for large assemblies or setups requiring precision and flexibility. It delivers strong, impact-resistant bonds to substrates like ABS, fiberglass, stainless steel, and aluminum, with minimal surface preparation. The black pigment improves visual control during alignment and inspection. Available in 50 ml and 490 ml cartridges.

Note: MMA 422 is also available in a cream/off-white color for applications requiring a neutral bond line.
