Plexus® MA1025 is a two-part methacrylate adhesive with very low cure shrinkage and very low odor designed for structural bonding of thermoplastic, metal, and composite assemblies1 . Combined at a 10:1 ratio, MA1025 has a working time of 20 to 25 minutes and achieves approximately 75% of ultimate strength in 40 to 45 minutes at 74°F (23°C). This product is the standard for structural bonding in the marine industry because it requires virtually no surface preparation. Plexus MA1025 is designed to be used for bonding stringers and liners into fiberglass boats with bond lines up to one inch thick. In addition, this product provides a unique combination of excellent fatigue endurance, outstanding impact resistance, and superior toughness. Plexus MA1025 is available in blue and is supplied in ready-to-use 380-ml cartridges, 5-gallon (20-liter) pails, or 50-gallon (200-liter) drums to be dispensed as a non -sagging gel.
