Abstract. The gas permeability of protective (sealing) liquids is the most important operational indicator, which determines the permeability of air oxygen through the coating film and the evaporation of water from under their layer. The results of the study of the evaporation of water located under a layer of sealing liquid are presented. The dependence of water evaporation on the composition and thickness of the sealing liquid layer on the water surface is established. It is shown that the sealing liquids, which include polyisobutylene of the P-200 brand, have the lowest gas permeability. The interrelation of gas permeability of sealing liquids with other operational indicators – thermal and oxidative stability, surface and protective properties is revealed/
