Infinity Bond MMA 330 Black Structural Adhesive for Extended Working Time Applications

Infinity Bond MMA 330 Black is a structural methacrylate adhesive formulated for projects that require longer setup times and high bond strength. With an 18 to 32 minute working time and 1:1 mix ratio, this adhesive is ideal for large assemblies, multi-component setups, or temperature-sensitive bonding environments. It delivers strong, durable bonds to aluminum, fiberglass, ABS, and other engineered plastics — all with minimal surface preparation. The black formulation offers enhanced visibility for alignment, inspection, or aesthetic consistency on the production line. Available in 50 ml and 400 ml cartridges.

Note: MMA 330 is also available in a off-white color for standard bonding applications.
