When exposed to a fire, Thermo-Lag E100 epoxy intumescent fireproofing, intumesces or swells, producing a heat blocking char layer, which insulates the steel. The intumescent reaction and subsequent char production slows the rate of steel temperature rise and allows it to maintain its strength longer. This increases the time for safe evacuation and fire-fighting measures in order to protect assets and save lives.
Thermo-Lag E100 was specifically designed to provide 1-3 hour cellulosic fire protection for commercial structural steel elements and has been certified in accordance with UL 263 / ASTM E119 / NFPA 251 fire test standards. It has successfully passed the UL environmental test program and has been rated for both exterior and interior use.
Thermo-Lag E100 offers high film build and fast recoat properties allowing applicators to apply the entire required thickness in minimal time.
