Abstract: A coating composition, a coating film, and a micro-channel type heat exchanger using the same are disclosed herein. The coating composition contains a hydrophilic resin at 10 to 40% by weight; a metal compound at 1 to 10% by weight; an amide-based crosslinking agent at 0.5 to 5% by weight; a phosphoric acid-based compound at 1 to 5% by weight; a preservative at 0.1 to 3% by weight; and water as a remainder. Thus, the coating composition provides a coating film that has both long-term corrosion resistance and long-term hydrophilicity.
