PlexusMA310 is a two-part methacrylate (MMA) adhesive designed for structural bonding of thermoplastic, metal, and composite assemblies. 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. 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. •No Surface Preparation •High Strength •High Modulus •100% Reactive •Excellent Tolerance to Off-Ratio Mixing •Non-Sagging Material characteristics: •Room Temperature Cure •Working Time 15 - 18 minutes •Fixture Time 45 - 55 minutes •Operating Temperature -67°F - 250°F (-55°C - 121°C) •Gap Filling 0.03 in. - 0.125 in.
