NoFire® is a one-part non-flammable water based intumescent fire-retardant coating similar in appearance to ordinary latex base paint. Upon exposure to flame or heat at temperatures in excess of 200°C (400 °F), it immediately foams and swells (intumesces) providing an effective insulation and heat shield to protect the subsurface, even at temperatures in excess of 1090°C (2000 °F).
