Every material has an ideally suited adhesive; some are easier to find that others. A new adhesive for metals has just been introduced. The Plexus Metal Bonder™ Adhesives deliver a unique combination of strength, fatigue endurance, impact resistance, and toughness on metals and other substrates including stainless steel, aluminum, thermoplastics, and composites. These two-part methacrylate adhesives are nonsagging gels formulated for metal bonding in off-highway applications such as bus and coach, RV, marine, heavy truck, trailer, and specialty vehicle manufacturing.
No primers and littler surface preparation are required. They are available with or without 12-mil solid glass bead spacers (for bond gap thickness control) and come packaged in ready-to-use cartridges, pails, and drums. They can be applied in bulk using Plexus FusionMate™ or other meter-mix dispensing systems.
Plexus MA830 has a working time of 4 to 6 minutes and a fixture time of 20 to 25 minutes. It cures at room temperature to a tensile strength of 3200-3800 psi (ASTM D638).
Plexus MA832 has a working time of approximately 14 minutes and a fixture time of approximately 55 minutes. It cures at room temperature to a tensile strength of 3500-4000 psi (ASTM D638).
