The protective, mechanical, dielectric and adhesive properties of "Cortecor 867" new coating are investigated before and after testing in 3 wt. % NaCl at t = -75°C in climate chambers, simulating a cold and moderately cold climate. It is shown that after prolonged testing the above properties are varied little from the impact of an aggressive environment and atmosphere. The calculated projected lifetimes of "Cortecor 867" coating are given in the conditions of the Far North and Eastern Siberia.
