THERMAL-RESISTANT POLYMER HEAT-REFLECTING COMPOSITION WITH LOW EMISSIVITY Russian patent published in 2017 - IPC C09D5/00 C08L83/04 

FIELD: chemistry.

SUBSTANCE: composition is described comprising a polymeric film former, a hardener, an aluminium paste, and a solvent, in which the silicone block copolymer in a toluene solution is used as a polymer film former, as a silicone amine curing agent, as a solvent, a xylene/butanol mixture, with the following component ratio, pts wt: silicone block copolymer 30-40, organosilicone amine 2.1-20, aluminium paste 30-40, xylene/butanol 100-300, toluene 60-70. The resulting composition cures at room temperature and has a reflection coefficient of, at least, 0.8 and a radiation coefficient of not more than 0.2 before and after exposure to a temperature of 500°C.

EFFECT: decreasing the emissivity.
