Phenolic epoxy resins are known for their unrivaled heat resistance and chemical stability. They are cured with phenolic epoxy hardeners. During this process, the hardener reacts with the phenolic resin’s epoxy groups forming a cross-linked polymer network. This product possesses outstanding thermal stability and can be exposed to high-temperature environments without degradation. In addition, phenolic epoxy hardeners enhance the chemical stability of phenolic epoxies which allows them to withstand the severe chemical conditions found in oil refineries, chemical processing plants, and high-temperature insulation materials.
