Plexus® MA422 is a two-part methacrylate adhesive designed for structural bonding of thermoplastic, metal, and composite assemblies. Combined at a 10:1 ratio, MA422 has a working time of 17 to 20 minutes and achieves approximately 75% of ultimate strength in 35 to 40 minutes at 74°F (23°C). Plexus MA422 is finding wide usage for composite bonding applications in the transportation and marine industries because it requires virtually no surface preparation. In addition, this product provides a unique combination of excellent fatigue endurance, outstanding impact resistance, and superior toughness. Plexus MA422 is blue when mixed and is supplied in a ready-to-use cartridge, 5-gallon (20 liter) pails, or 50-gallon (200-liter) drums to be dispensed as a non-sagging gel.
