Abstract Epoxy powder coating resistance to corrosion medium in high temperature solution is investigated using static immersion method and infrared spectroscopy, analyz ed medium transport behavior between 100℃ to 120℃ and between 100℃.Experience results show:(1)When the medium temperture is higher than Tg,epoxy powder coating resistance to corrosion medium is worse.When the medium temperature is lowe r than Tg, Epoxy powder coating resistance to corrosion medium is better.( 2)Epoxy powder coatings in high temperature solution(100℃≤T≤120℃)have sa me good alkali-resistance as that in low temperature solution(T＜100℃).

Key words: epoxy resin coating permeability infrared spectroscopy
