The effect of mineral filler compounds on vapor permeability and hygroscopic properties of water-based polymer dispersions and the possibility of their use as decorative and protective material for stucco facades finishing was studied. According to Facade Protection Theory (H.M. Künzel), the assessment criterion was vapor permeability and water vapor diffusivity. The pairwise correlation of building physical properties of water-based polymer dispersions in the coordinates of Künzel's diagram clearly demonstrates that, in terms of hygroscopic, all the samples studied correspond to the low hygroscopic class, and in terms of vapor, they are close to high water vapour diffusion rate class.

In marine conditions, especially in the Arctic, the problems of reliability and safety of marine corrosion protection systems are relevant. Reliability can be enhanced by corrosion inhibitors. For the equipment not subject to painting, safe technologies for preservation of water-based compounds are substantiated by bioassay methods. When carrying out painting work carried out by crew members at sea, a simplified chemical surface preparation was proposed with the «NOTEH» phosphating compound with anode inhibitors. The topic of the discussion are the passivation properties of «NOTEH» according to the data on the suppression of corrosion under a layer of paint primer. To increase the safety of work, hexavalent chromium compounds were removed from the inhibiting block of «NOTEH» additives.
