FIELD: chemistry.
SUBSTANCE: composition consists of 90-96 wt % of a base - mixture of polydimethylsiloxane (40-60 wt %) and polymethylphenylsiloxane (60-40 wt %) liquid with viscosity of 3000-40000 mm2/s at temperature of 20°C and 4-10 wt % thickener - silicon dioxide. The composition has a refraction index of 1.4100-1.4300, penetration value of 160-280 units, and operates in the temperature range from (-70°C) to (+300°C).
EFFECT: improved properties of the composition.
