FIELD: protection of thermally regulating galvanochemical coatings in aviation instrument making, against corrosion and atmospheric effect of air. SUBSTANCE: described is removable coating comprising, as composition substrate, polyvinyl alcohol, distilled water, urea as atmospheric corrosion inhibitor, and sorbitol as plasticizer. Coating further comprises modifying filler of tixotropic activity e.g. ethyl silicate, ratios of components being as follows, wt %: polyvinyl alcohol, 10-11; urea, 0.05-0.1; sorbitol, 0.2- 0.3; ethyl silicate, 0.02-0.07, distilled water balance, up to 100%. EFFECT: greater strength, improved adhesion strength and longer service life of the coating. 1 tbl
