Plexus MA310 All Purpose High Strength MMA Adhesive (31500, 31000)

Plexus MA310 is a two-part methacrylate adhesive designed for structural bonding of thermoplastic, metal, and composite assemblies. Combined at a 1:1 ratio, MA310 is a medium-curing adhesive system. MA310 offers a combination of high strength and stiffness as well as the ability to bond a wide range of materials. Plexus MA310 is supplied in ready-to-use 50-ml and 400-ml cartridges, 5-gallon (20-liter) pails, or 50-gallon (200-liter) drums to be dispensed as a non-sagging gel.

Plexus MA310 replaces an older popular Devcon formula Plastic Welder 2 (14340). It is the same formula inside, but is now branded under the ITW Plexus name.
