Infinity Bond MMA 832 Flexible Methacrylate Adhesive for Dynamic Bonding Applications

Infinity Bond MMA 832 is a flexibilized, two-part methacrylate adhesive designed to create impact-resistant structural bonds between metals, plastics, and composites. With a 10:1 mix ratio and an 12–15 minute working time, it’s ideal for assemblies that need to accommodate movement or vibration. This adhesive reaches 90% of its bond strength in under 25 minutes and requires little to no surface preparation.

MMA 832 is particularly well-suited for bonding dissimilar substrates where differences in thermal expansion (CTE) are a concern. It forms high-strength, flexible bonds to aluminum, stainless steel, fiberglass, and a variety of plastics while offering excellent gap-filling and elongation properties.
