Epoxy 828 – General Grade Epoxy Resin

828 Resin / SM828 also known as Epoxy 828, is a high-performance, undiluted difunctional bisphenol-A liquid epoxy resin. It offers excellent mechanical strength, strong adhesion, good dielectric properties, and reliable chemical resistance once cured with a suitable hardener. Because of this versatility, SM828 is one of the most widely used standard epoxy resins across formulation, fabrication, and lamination processes.

SM828 requires a suitable hardener to cure into its final form. BosTech Polymer supplies a full range of compatible epoxy hardeners, including REH 115, REH 140, REH 160, REH 243, and REH 7301, each suited to different cure speeds and end-use requirements. DMP-30 is also available as an accelerator to speed up curing where needed.
