Useful links: Safety data sheets: - Curing Agent Epoxy novolac resins generally contain more epoxy groups per molecule compared to standard epoxy resins. This means epoxy novolac resins achieve stronger chemical bonding during the chemical process, which results in excellent temperature, chemical and solvent resistance.
