Description
Plexus MA1023 is a blue, two-part methacrylate (MMA) structural adhesive supplied in a 5 gallon pail. It bonds a wide range of metals, composites, and thermoplastics with minimal surface prep, which makes it a workhorse for fabrication shops building transportation, marine, and industrial assemblies. The color makes mix verification easy, since a uniform blue tells the operator the resin and activator are fully combined.
Plexus MA1023 performance
This grade runs a 10:1 mix ratio and delivers a working window with a fixture time around 20 to 25 minutes, giving crews time to position parts before the bond locks in. Cured strength lands in the 1750 to 2000 psi tensile range, and the methacrylate chemistry holds up across an operating range from roughly -40°F to 180°F, so joints stay sound through temperature swings and vibration. The toughened acrylic chemistry also resists peel and impact loads better than rigid epoxies, which helps on assemblies that flex or carry dynamic loads in service.
Plexus MA1023 application and handling
Dispense the Plexus MA1023 adhesive through matched meter-mix equipment or a static mixer nozzle sized for a 10:1 cartridge or bulk system. Surfaces should be clean and dry, though MMA chemistry tolerates light oils better than many epoxies. Confirm the activator is within shelf life, and review the manufacturer technical data for cure schedule and substrate guidance before a production run. Running a small adhesion test on production substrates is good practice whenever you switch materials or coatings.
The 5 gallon pail suits shops consuming adhesive at volume rather than in cartridges.
