Plexus® MA920 Low-Odor Adhesive

Request Quote Request Sample

Plexus® MA920 is a low-odor two-part methacrylate adhesive designed for structural bonding of thermoplastic, metal and composite assemblies. MA920 is a breakthrough in methacrylate adhesive technology because it combines high strength, excellent fatigue endurance, and outstanding impact resistance into a low odor product. Mixed at a 10:1 ratio, MA920 has a working time of 4 to 6 minutes and achieves approximately 75% of ultimate strength in 15 to 18 minutes at 74°F (23°C). Plexus MA920 requires virtually no surface preparation on most substrates. Plexus MA920 is blue when mixed and is supplied in a ready-to-use cartridge, 5-gallon (20-liter) pails, or 50-gallon (200-liter) drums to be dispensed as a non-sagging gel.
