Methyl Methacrylate (MMA) Adhesives

These Methyl Methacrylate Adhesives are designed for bonding metals, composites, and other plastic parts. They are two-component, 100% reactive, and formulated for excellent impact, peel, and shear resistance. Most metals can be bonded without primer. What Are Methyl Methacrylate (MMA) Adhesives? Methyl Methacrylate (MMA) adhesives are two-component, 100% reactive structural adhesives for bonding metals, composites, and plastic parts. Because they are 100% reactive, there is no solvent to flash off. They are formulated for excellent impact, peel, and shear resistance, and most metals can be bonded without a primer. Fibre Glast stocks SciGrip SG 300-40, a Seakeeper approved alternative to Plexus. Why Choose MMA Adhesives? MMA bonds a wide range of substrates including thermoset composites such as vinyl ester, polyester, gel coats, and epoxy, as well as metals and plastics. It delivers excellent fatigue, impact, and shock load resistance along with environmental resistance in harsh operating conditions, making it suited to joints that must survive vibration and repeated loading. Bonding most metals without primer simplifies production assembly compared to adhesives requiring a separate primer step. What Are the Best Applications for MMA Adhesives? Automotive components, marine assemblies, appliances, metal assemblies, plastic fabrications, and composite assemblies. SciGrip SG 300-40 is the right choice wherever dissimilar materials such as metal and composite must be joined into a durable, load-bearing bond. For thick, gap-filling epoxy paste for fixtured sub-assemblies, see the #1101 Epoxy Paste Bonding Adhesive. How Should MMA Adhesives Be Used for Best Results? SciGrip SG 300-40 is supplied in 490 ml cartridges and mixes at a 10:1 ratio through a dispensing system. The Black SG 300-40 has a 40-minute working time; plan the assembly to be fixtured within that window. Bond clean, properly prepared substrates. No primer is required on most metals.
