Product Name

PLEXUS MA2245 - 490ml 10:1 Ratio Cartridge - Blue

Brief Description

Plexus MA2245 is a two-part methacrylate adhesive engineered for the structural bonding of thermoplastic, metal, and composite assemblies. It is combined at a 10:1 ratio and supplied as a non-sagging gel, available in blue or black colors.

Popular Applications & Uses

- Structural bonding of diverse assemblies, including composites, thermoplastics, and metals.- Ideal for composite bonding applications within the marine and transportation industries.- Effective for filling gaps ranging from 0.03 inches to 1.5 inches (0.75 mm to 38 mm).

Industries that Commonly Use It

- Marine- Transportation/ Specialty Vehicle- General Manufacturing- Metal Fabrication- Plastic Fabrication- Fabrication

Special and Unique Features

- Requires virtually no surface preparation for many substrates.- Offers excellent fatigue endurance.- Provides outstanding impact resistance.- Exhibits superior toughness.- Features low shrink technology.- Highly thixotropic, allowing for the dispensing of large, non-sag beads.- Characterized by an extremely low exotherm during cure.- Cures at room temperature.
