Abstract: The fireproofing coatings with the flame spread index and smoke generation in-dex, hydrocarbon fire resistance and durability were studied. It was found that the borates-free epoxy fireproofing coatings with 10 mm film thickness could resist hydrocarbon fire for 160 min according to GA/T 714-2007. As exposed to various environments, the coatings showed the fire resistance time decreased less than 15% according to GB 14907-2002 and ANSVUL 1709-2007, indicating that the coatings were applicable to the high buildings, chemical facto-ries and offshore oil platforms.
