Plexus® MA2290 Two-part Methacrylate Adhesive

Plexus® MA2290 is a two-part methacrylate adhesive designed for structural bonding of thermoplastic, metal, and composite assemblies. Combined at a 10:1 ratio, Plexus MA2290 is an excellent choice for composite bonding applications in the marine and transportation industries because it requires virtually no surface preparation and can fill Gaps from 0.03 inches to 1.5 inches* (final Gap fill is dependent on laminate thickness and composition). In addition, this product provides a unique combination of excellent fatigue endurance, outstanding impact resistance, and superior toughness. Plexus MA2290 is available in blue or black colors and is supplied in 5-gallon (20-liter) pails, or 50-gallon (200-liter) drums to be dispensed as a non-sagging gel.
