Plexus® MA2045 Two-part Methacrylate Adhesive

Plexus® MA2045 is a two-part methacrylate adhesive designed for structural bonding of composite, thermoplastic, and metal assemblies. MA2045 was uniquely formulated to eliminate problems associated with adhesive sag and slide, even when applied to a vertical surface. In addition, MA2045 does not boil in gaps up to 1.5 inches thick. Combined at a 10:1 ratio at 75°F (24°C), it has a working time of approximately 50 minutes and achieves 500 psi and 1000 psi in approximately 100 and 130 minutes, respectively. As with most other Plexus methacrylate systems, MA2045 requires little-to-no surface preparation. MA2045 provides a unique combination of excellent fatigue endurance, outstanding impact resistance, and superior toughness. MA2045 is supplied in 380-ml cartridges, 5-gallon (20-liter) pails, or 50-gallon (200-liter) drums to be dispensed as a non-sagging gel.
