Description
The Plexus® MA300 25 ml cream cartridge is a compact, dual-component methacrylate structural adhesive engineered for high-strength bonding of thermoplastics, composites, and metals. With a 1:1 mix ratio, the 25 ml cartridge is ideal for small repairs, prototypes, or sample bonding where precision and minimal material waste are critical. This adhesive cures quickly, reaching 500 psi in about 11–13 minutes and 1,000 psi in 13–16 minutes at 74 °F (23 °C), making it a fast, reliable solution for assembly and repair tasks.
