FIELD: process engineering.
SUBSTANCE: invention relates to complex protection of glazed, ceramic and metal surfaces of electric devices. This method of complex protection is intended for at least glazed, ceramic or metal surfaces of electric devices and made with protective film to be applied on electric and insulating parts thereof. It comprises preparation of surface consisting in cleaning and degreasing and applying a composite compound based on fluoride-bearing surfactant and thermal fixation of the film made thereby.
EFFECT: complex protection against current leaks, corrosion, caking and other harmful effects at operating temperatures of -60°C to 520°C (short-term cyclic effects, of up to 800°C) at voltage of over 20000 volts, hydrophobisation of the article.
