| Abstract: | It exists the contradiction between the required temperature of lower than 200℃ in the anticorrosion coating of high yield strength steel pipe （above X80） and the heating temperature of 240 ℃ before applying the FBE primer of FBE anticorrosion coatings, HPCC or 3LPE systems. We adopt our self-made Amanda979 curing agents, together with selected epoxy resin, fillers and additives, to give anticorrosion epoxy powder coatings for X80 steel pipe. Test results show that the coatings can be cured in 2-3min under the temperature of 80-185 ℃, with perfect adhesion, high temperature cathodic peeling resistance （ testing 30d under 1.5 V/65 ℃, radius being 〈 10 mm）, meeting the technical requirements of new FBE pipeline anticorrosion coating. |
