PLEXUS MA830 - 5 Gallon Pail Activator- Gray

Product Name

PLEXUS MA830 - 5 Gallon Pail Activator- Gray

Brief Description

Plexus MA830 is a two-part methacrylate adhesive system designed for high-strength structural bonding. This specific product is the grey-colored Activator (Part B) component, which, when combined with the adhesive (Part A) at a 10:1 ratio, facilitates rapid curing and forms durable bonds. It is engineered for primerless adhesion to a wide range of metals, thermoplastics, and composite assemblies.

Popular Applications & Uses

- Structural bonding of various metals, including aluminum, stainless steel, raw steel, and coated metals.- Adhering a wide array of thermoplastics such as ABS/ABS Blends, Acrylics, PBT, Polycarbonate, Rigid PVC, and TPU.- Bonding composite materials like DCPD, FRP, Gelcoat, Phenolics, Epoxy Based Composites, and RIM.- Applications in the marine industry for deck-to-hull, liners, and composite stringers.- Used in the transportation sector for bus, train, and truck manufacturing and repair.

Industries that Commonly Use It

- Aerospace/Defense- Automotive Service/Repair- Construction/Building Services- Fabrication- General Manufacturing- Marine- Metal Fabrication- Plastic Fabrication- Transportation/Specialty Vehicle

Special and Unique Features

- Achieves primerless adhesion to many metals, most thermoplastics, and composites, simplifying surface preparation.- Offers a unique combination of high strength, excellent fatigue endurance, outstanding impact resistance, and superior toughness.- Features a fast working time of 4 to 6 minutes and achieves approximately 75% of ultimate strength in 15 to 25 minutes at 23°C (74°F).- Supplied as a non-sagging gel, suitable for dispensing with standard meter-mix equipment.- Provides excellent chemical resistance to hydrocarbons, acids and bases (pH 3-10), and salt solutions.
