FIELD: electric engineering, radio-electronics, possible use during manufacture of high frequency electronic boards, used for building radio-electronic equipment meant for operations under conditions of increased moisture and biological pollution levels.
SUBSTANCE: in accordance to invention, biocide admixture Traetex-243 is introduced to silicon-organic composition with low tangent if angle of dielectric losses tg≤1·10-3, with following weight ratio of components in percents of mass: silicon-organic composition - 99,0-99,5, biocide admixture - 0,5-1,0.
EFFECT: suggested polymer organic-silicon cover protects electronic boards and radio elements positioned on them from effect of high frequency currents, moisture and makes them resistant to biological pollution.
