A corrosion resistant coatings under insulation was prepared by using epoxy-silicone resin modified epoxy novolac resin. The coatings properties were analyzed by TGA，DMA，DSA methods and so on. The influence of different resin ratio，types of curing agent，and fillers on heat resistance，mechnical properties and corrosion protection were also studied. Test results showed that the modification ratio of epoxy-silicone resin to epoxy novolac resin at 4∶6 could improve the coating′s heat resistance performance effectively. By using this resin as binder，and modified cycloaliphatic amine as curing agent，lamellar red micaceous iron oxide as the main pigment，the obtained coatings showed good mechanical properties，thermal resistant properties and anti-corrosion properties. The coatings has also met the requirement for CUI thermal cycling test at 250 ℃.
