PLEXUS MA2290 - 5 Gallon Pail Adhesive

Product Name

PLEXUS MA2290 - 5 Gallon Pail Adhesive

Brief Description

Plexus MA2290 is a two-part methacrylate adhesive engineered for the structural bonding of thermoplastic, metal, and composite assemblies. It features a 10:1 mix ratio and is known for its ability to create durable bonds with minimal to no surface preparation.

Popular Applications & Uses

- Structural bonding of composite assemblies in marine and transportation industries.- Panel bonding, reinforcement bonding, and bracket & accessories bonding.- Replacement for traditional fastening methods like welding and riveting.- Bonding floating floors and modular washrooms in railway carriages.- Adhering composite body panels on buses and coaches, as well as doors, headlamp surrounds, and front grills for trucks.- Manufacturing of wind blades, turbine housing assemblies, and lightning suppression systems in the wind energy sector.- Composite stringers, liners, and deck to hull bonding in marine applications.

Industries that Commonly Use It

- Marine- Transportation/ Specialty Vehicle- General Manufacturing- Energy (specifically Wind Energy)- Aerospace/Defense- Construction/ Building Services- Metal Fabrication- Plastic Fabrication

Special and Unique Features

- Requires virtually no surface preparation, reducing dust emissions and increasing production speed.- Excellent fatigue endurance, outstanding impact resistance, and superior toughness.- Provides lower exotherm and shrinkage compared to similar acrylic adhesives, mitigating read-through/printing.- Highly thixotropic, allowing for dispensing large non-sag beads.- Low shrink technology.- Can fill gaps ranging from 0.03 inches to 1.5 inches.- Available in blue or black colors.
