PLEXUS MA320 - 50 Gallon Drum Adhesive

Product Name

PLEXUS MA320 - 50 Gallon Drum Adhesive

Brief Description

Plexus MA320 is a two-part methacrylate adhesive engineered for the structural bonding of thermoplastic, metal, and composite assemblies. It is recognized for its high strength, exceptional durability, and superior toughness, even in low-temperature environments, often requiring minimal surface preparation.

Popular Applications & Uses

- Structural bonding of diverse materials including composites, thermoplastics, and metals.- Composite bonding applications in various industries.- Deck-to-hull, liners, and composite stringer bonding in the marine industry.- Manufacturing of wind turbine components such as wind-blades, nacelle housings, and lightning suppression systems.- Assembly in the bus and train industries.- General assembly and manufacturing processes.

Industries that Commonly Use It

- Aerospace/Defense- Cladding- Construction/ Building Services (specifically engineering construction)- Countertop- Energy (particularly wind energy)- Engineering Services- General Manufacturing- Marine- Metal Fabrication- Plastic Fabrication- Sign & Display (for structural bonding in sign manufacturing)- Transportation/ Specialty Vehicle (including bus and train industries)

Special and Unique Features

- Two-part methacrylate adhesive system.- Features a 10:1 mix ratio.- Delivers high strength and durability for robust bonds.- Provides superior toughness, maintaining performance even at low temperatures down to -67°F (-55°C).- Typically requires minimal to no surface preparation, simplifying application.- Achieves fast and consistent strength development at room temperature.- Exhibits high elongation and excellent stress distribution, beneficial for dissimilar material bonding.- Dispenses as a non-sagging gel, allowing for precise application.- Offers excellent chemical resistance to salt solutions, bases (pH 3-10), hydrocarbons, and acids (pH 3-10).- Available in off-white, white, or black colors.
