The conventional properties of the TJ 1357-6 red surface insulating paint were introduced.In addition,the viscosity-temperature change curve of the surface insulating paint,the influence of drying mode on the film performance,the influence of temperature on the potlife and the matching of the surface insulating paint were studied.The results show that the TJ 1357-6 red surface insulating enamel has excellent water resistance,heat and humidity resistance,acid and alk ali resistance,salt fog resistance,artificial accelerated aging resistance and electrical performance.It had good compatibility with the impregnating varnish.The appearance of the composite coating was uniform and the adhesion reached 0 level.
