Plexus® MA832 is an advanced two-part methacrylate adhesive designed for structural bonding of metals without primers. In addition, MA832 does a superb job of bonding thermoplastic and composite assemblies with little to no surface preparation. Combined at a 10:1 ratio, MA832 has a working time approximately 12 to 14 minutes and achieves approximately 500 psi (3.5 MPa) in 65 to 70 minutes. This product provides a unique combination of high strength, excellent fatigue endurance, outstanding impact resistance, and superior toughness. Plexus MA832 is available in grey and is supplied in a ready- to-use cartridge, 5-gallon (20-liter) pails, or 50-gallon (200-liter) drums to be dispensed as a non- sagging gel.
