Description
Advanced two-part methacrylate adhesive designed for structural bonding of metals without primers. In addition, Plexus MA832 does a superb job of bonding thermoplastic and composite assemblies with little to no surface preparation.
And for reference, GB means Glass-Bead infused formula.
MA832 is the standard formulation
and MA832 GB has glass micro-beads infused into the formula to maintain/enforce a minimum optimal bondline. It is a popular feature for performance bonding processes.
