PLEXUS MA832 & MA832 GB Advanced Two-part Methacrylate Adhesive

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.
