MMA 832 Impact Resistant Methacrylate Adhesive – 14 Minute Open Time

Overview of Infinity Bond MMA 832

Infinity Bond MMA 832 is a two-part methacrylate, flexibilized structural bonding adhesive designed for various substrates, including fiberglass, steel, aluminum, and various plastics (excluding low-energy surfaces). Combined at a ratio of 10:1, MMA 832 has a working time of 8 to 12 minutes and reaches nearly 90 percent of its ultimate strength within 18 to 25 minutes at room temperature.

MMA 832 provides high strength and very flexible bonds to these surfaces, typically requiring no preparation. It bonds very strongly to steel, stainless steel, and aluminum, accommodating significant movement of the substrates due to differences in the Coefficient of Thermal Expansion (CTE).
