HEAT-RESISTANT PROTECTIVE ORGANOSILICATE COATING FOR NUCLEAR POWER STATION Russian patent published in 2021 - IPC C09D183/00 

FIELD: coatings.

SUBSTANCE: invention relates to polymeric anticorrosive, radiation-resistant, decontaminated, heat-resistant coatings. The heat-resistant protective organosilicate coating for nuclear power stations comprises an organosilicon binder in form of unmodified polydimethylphenylsiloxane, a silicate filler in form of chrysotile asbestos and mica, and pigments. The coating is made at the following ratio of components by dry residue (% wt.): unmodified polydimethylphenylsiloxane - 64 to 67, chrysotile asbestos - 14 to 16, mica - 14 to 16, pigments - 3 to 5. The mass ratio of the polymer to the silicates therein does not exceed 2.24:1. The sum total of silicate components - chrysotile asbestos and mica - is 30 to 31% wt.

EFFECT: invention ensures maintained heat resistance of the coating up to 300°C with improved decontaminating properties.
