Description
Plexus® MA832 Structural Methacrylate Adhesive (490ml Cartridge)
Plexus® MA832 is a high strength structural MMA adhesive designed for fast, reliable bonding of metals, plastics and composites in demanding industrial environments.
Engineered for primerless metal bonding, MA832 significantly reduces preparation time while delivering exceptional bond strength and durability. It also performs outstandingly on thermoplastics and composite materials, often requiring little to no surface preparation, making it ideal for both production and on-site applications.
🚀 Key Benefits
- High strength structural adhesive for load-bearing applications
- Primerless bonding to metals – reduces labour and consumables
- Excellent impact and fatigue resistance for long-term durability
- Fast cure profile – ideal for production and time-sensitive jobs
- Gap filling up to 13mm – handles imperfect surfaces with ease
- Bonds mixed substrates including metal to plastic and composites
⚙️ Performance & Working Properties
Mixed at a 10:1 ratio, Plexus MA832 provides a practical working time of approximately 12–14 minutes, allowing for accurate positioning and assembly.
- Achieves ~500 psi (3.5 MPa) in 55–70 minutes
- High ultimate tensile strength (up to 3,410 psi / 23.5 MPa)
- Non-sag gel formulation for vertical and overhead applications
- Designed for consistent dispensing using standard cartridge systems
This balanced performance makes MA832 ideal for applications where strength, speed and reliability are critical.
