Plexus MA420 (also known as AO420) is a two-part methacrylate adhesive designed for structural bonding of thermo plastic, metal and composite assemblies. Combined at a 10:1 ratio is a rapid curing system and is the standard choice for composite bonding applications in the transportation industry because it requires no surface preparation.
