Product Description
Plexus® MA820FS is a high-performance, two-component acrylic adhesive engineered for structural bonding of plastics, metals, and composites with minimal surface preparation. With a 10:1 mixing ratio, this adhesive delivers high strength, excellent fatigue resistance, impact resistance, and superior toughness. It offers a fast working time of 3 to 5 minutes and achieves approximately 75% of its final strength within 8 to 10 minutes at room temperature. The non-sagging formula ensures precision in application. Available in 380ml cartridges, 5-gallon barrels, and 50-gallon drums, Plexus® MA820FS is an efficient solution for industrial bonding applications.
