ITW Plexus® MA8110 Methacrylate Adhesive
Categories:	Polymer; Adhesive; Thermoset; Methacrylate; Methacrylate Adhesive
Material Notes:	Plexus® MA8110 is a two-part methacrylate adhesive designed for structural bonding of galvanized metal assemblies. Combined at a 1:1 ratio, MA8110 is a fast-curing system. Plexus MA8110 is designed primarily for bonding galvanized coated metals, in particular Hot Dipped G90 and G60, but may be used like most Plexus adhesives, bonding other metals and dissimilar materials with little to no surface preparation. In addition, this product provides a unique combination of excellent fatigue endurance, outstanding impact resistance, and superior toughness. Plexus MA8110 is available in gray and is supplied ready-to-use to be dispensed as a non-sagging gel. Excellentl resistance to: ? Acids and Bases (pH 3-10)? Salt Solutions. Susceptible to:? Polar Solvents? Strong Acids and Bases. Recommended for: ? Hot dipped G60 & G90 ? Other Zinc coated metals ? FRP ? Thermoplastics ? Gel coat ? Polyesters (including DCPD modified) ? Urethanes (general) ? Vinyl Esters ?Aluminum ? Steel, Carbon & Stainless. Adhesive color: off white (uncured-room temperature). Activator color; gray (uncured-room temperature).
