Novolac epoxy resin is semi-solid reaction product of epichlorohydrin and phenol-formaldehyde novolac. It possesses excellent corrosion resistance, chemical resistance, heat resistance, and high insulation properties.It primarily used in fields such as copper-clad laminates, vinyl resin, inks, insulation materials, heavy-duty anti-corrosive coatings, adhesives, etc.
