Plexus MA 300 All Purpose High Strength Adhesive - Universal Cartridge

Plexus MA 300 is a two-part methacrylate adhesive designed for structural bonding of thermoplastic, metal and composite assemblies. The universal cartridge fits any standard caulking gun, and is Cream in color.

Plexus 300 is one of the more commonly used adhesives for a number of reasons. It adheres to most substrates. It has a simple one-to-one mix ratio. Rapid cure time means quick repairs, yet MA 300 has nearly three times the tensile strength of 3M 5200.

Many professional boatbuilders use MA 300 and swear by it. Includes one mixing nozzle for easy 1:1 mix ratios.

MA 300 may be applied manually or with automated equipment. Automated application may be accomplished with a variety of 1:1 meter-mix equipment delivering both components to a static mixer. To assure maximum bond strength, surfaces must be mated within the specified working time. Use sufficient material to ensure the joint is completely filled when parts are mated and clamped. All adhesive application, part positioning, and fixturing should occur before the working time of the mix has expired. After indicated working time, parts must remain undisturbed until the fixture time is reached. Automated equipment should be constructed of stainless steel or aluminum. Avoid contact with copper or copper containing alloys in all fittings, pumps, etc. Seals and gaskets should be made of PTFE, PTFE-coated PVC foam, ethylene/propylene or polyethylene.
