Overview of the MMA 300 High-Performance Methacrylate Adhesive
Infinity Bond MMA 300 is a high-strength, fast-curing methyl methacrylate structural adhesive designed for bonding fiberglass, steel, aluminum, and various plastics (excluding low-energy surfaces). It features a 1:1 mix ratio, a 3 to 6-minute working time, and a 10 to 15-minute fixture time. It provides rapid strength development and achieves nearly 90% of its ultimate bond strength in just minutes.
MMA 300 delivers exceptional impact resistance, making it ideal for demanding applications. It withstands extreme temperature fluctuations (thermal cycling) and maintains bond integrity under harsh environmental conditions. Unlike some adhesives, MMA 300 requires minimal surface preparation, making it a preferred choice for manufacturing, product assembly, and industrial repairs.
