Plexus® MA530 is a two-part methacrylate adhesive designed for structural bonding of thermoplastic, metal, and composite assemblies. Combined at a 1:1 ratio, MA530 has a working time of 30 to 40 minutes and reaches approximately 500 psi in 90 to 110 minutes and 1000 psi in 150 to 160 minutes at 274˚F (23˚C). This product has been designed for use on large structures where a moderate open time product is needed. Plexus MA530 may be used for composite and metal bonding for small to large structures. In addition, this product provides a unique combination of excellent fatigue endurance, outstanding impact resistance, and superior toughness. Plexus MA530 is gray when mixed and is available in ready-to-use 400-ml cartridges, 5-gallon (20-liter) pails, or 50- gallon (200-liter) drums to be dispensed as a non-sagging gel.
