The drying time of each layer to the third degree at twenty degrees does not exceed one hour. Up to the fifth degree, the agent will dry overnight.

For use, a certain viscosity of a substance, such as varnish ХВ-784, is required. Its technical characteristics will be preserved if P-4 is used as the solvent.
