Infinity Bond MMA 320 Black Structural Adhesive for Flexible Bonding Applications
Infinity Bond MMA 320 Black is a flexible, high-strength structural adhesive designed to bond metals, plastics, and composites — even in demanding, high-movement applications. With an 8 to 12 minute working time and 10:1 mix ratio, it provides excellent strength and elongation while accommodating thermal expansion and vibration. It adheres exceptionally well to materials like fiberglass, ABS, aluminum, and stainless steel with minimal surface preparation. The black pigment offers visual contrast for inspection, part alignment, or aesthetic consistency in assembly environments. Available in 50 ml and 490 ml cartridges.
Note: MMA 320 is also available in a cream/off-white color for standard bonding applications.
