NOVELTY - Coating comprises A component and B component. The component A includes 4.7- 5 pts. wt. aqueous epoxy curing agent, 0.4-0.5 pts. wt. dispersant, 0.1- 0.2 pts. wt. antifoaming agent, 3.7-4.0 pts. wt. cosolvent 1, 3.7-4.0 pts. wt. cosolvent 2, 0.4- 0.5 pts. wt. powder I, 0.59-0.65 pts. wt. powder II, 1-5 pts. wt. high heat-conducting anti-corrosion additive, 11-16 pts. wt. filler, 44-48 pts. wt. zinc powder. The component B includes 19-22 pts. wt. aqueous epoxy emulsion, 0-5 pts. wt. high heat-conducting anticorrosion additive, 0-1.2 pts. wt. deionized water mixing the A component and the B component to obtain the coating for transformer. USE - The coating is useful for transformer, which is used for electric energy conversion, conveying and distribution in the power system. Also used in power transmission and transformation device to the environment. ADVANTAGE - The coating is environmentally friendly, with high heat conductivity and corrosion resistance, improving the radiating performance of the transformer, enhancing the adaptability of the power transmission and transformation device to the environment.
