| Plexus® MA560-1 is a two-part methacrylate adhesive designed for structural bonding of thermoplastic, metal, and composite assemblies. Combined at a 1:1 ratio, MA560-1 has a working time of 55 to 70 minutes at room temperature and at 74°F (23°C). MA560-1 reaches lap shear values of approximately 500 and 1000 psi in 3 and 4 hours, respectively, at a 0.03-in. (0.75-mm) bond line. This product has been designed for use on large structures where a very long open time product is needed. Plexus MA560-1 is commonly used for bonding stringers and liners into large fiberglass boats with bond lines up to 1.00 in. (25 mm) thick. In addition, this product provides a unique combination of excellent fatigue endurance, outstanding impact resistance, and superior toughness. Plexus MA560-1 is gray when mixed and ready-to-use to be dispensed as a non-sagging gel. Excellent chemical resistance to: ? Hydrocarbons ? Acids and Bases (pH 3-10) ? Salt Solutions. Susceptible to: ? Polar Solvents ? Strong Acids and Bases. Recommended for: ? ABS ? Acrylics ? FRP ? Gel coats ? PVC? Polyesters (including DCPD modified) ? Stainless Steel ? Aluminum ? Styrenics ? Urethanes (general) ? Vinyl Esters (Exterior applications require the use of coatings or primers that inhibit oxidation of the metals.). Adhesive color: white. Activator color: black/white.
