Overview of Plexus MA330 Adhesive MA330 is a two-part methacrylate adhesive designed for structural bonding of thermoplastic, metal, and composite assemblies1. Combined at a 1:1 ratio, MA330 has a working time of 15 to 18 minutes and achieves approximately 75% of ultimate strength in 30 to 45 minutes at 74°F (23°C). MA330 offers a combination of high strength and stiffness as well as the ability to bond a wide range of materials.
