Description
Plexus MA300 is a two-part methacrylate adhesive designed for structural bonding of thermoplastic, metal, and composite assemblies. Combined at a 1:1 ratio, MA300 has a working time of 3 to 6 minutes and reaches approximately 500 psi in 20 minutes and 1000 psi in 35 minutes at 74°F (23°C). This product offers a combination of high strength and stiffness as well as the ability to bond a wide range of materials. Plexus MA300 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
