FIELD: electrical engineering.
SUBSTANCE: suggested varnish coating protects printed circuit board and units of radio-electronic equipment, which are installed on it, against effect of different external factors that cause corrosion and against bacteria that cause fungi growth. Protective coating for printed circuit boards contains epoxy urethane varnish with hardener and biocide additive Traetex-243, with the following ratio of components, in %: epoxy urethane varnish with hardener - 99.00-99.75, biocide additive Traetex-243 - 0.25 - 1.00.
EFFECT: increase of electric insulation properties and resistance to fungi growth.
