Description
The Plexus® MA300 50 ml cream cartridge is a two-part methacrylate structural adhesive designed for high-strength bonding of thermoplastics, metals, and composites. Packaged in a mid-size dual cartridge, it’s perfect for manufacturers, installers, and field technicians who need a versatile adhesive for small to medium bonding tasks. With a 1:1 mix ratio and a 3–6 minute working time, this adhesive allows easy part alignment and rapid fixture. It develops 500 psi in about 11–13 minutes and 1,000 psi in 13–16 minutes at 74 °F (23 °C), making it an excellent choice for fast-paced assembly environments.
