FIELD: spatial material science and optical engineering. ^ SUBSTANCE: invention is designed for use in system of passive thermoregulation of spatial apparatuses for manufacturing cold-drying coatings of class "sun reflectors", which are applied onto outer surfaces of spatial apparatuses. Composition according to invention comprises: 9.49-9.54 wt parts amide-containing acrylic resin as binder; 52.36-52.49 wt parts monocrystalline superfine white-colored powder of zinc-gallium oxide with calculated formula ZnGaO1+n, wherein n=0.0064, and molecular mass 81.38; and 37.99038.15 wt parts solvent: xylene/butanol mixture at ratio 4:1; provided that binder-to-filler ratio is 1:5.5 and fraction of nonvolatile substances is 58.0% maximum. ^ EFFECT: preserved high optical characteristics of coating during prolonged operation of spatial apparatus. ^ 3 cl, 1 dwg, 3 tbl |
