    The invention relates to a method for producing coatings for various surfaces, for sealing seams and sealing, and can be used in various industries. s
    A known method for producing coatings by reacting a product containing aliphatic and / or cycloaliphatic isocyanate groups with a fermentor. The method involves the use of blocked isocyanates, and as a hardener diimine p.
    But the process of curing these compositions occurs relatively slowly and largely depends on temperature. So, during synthesis under normal climatic conditions, the curing process takes place within 24 hours.
    The aim of the invention is to accelerate the film formation and improve the strength characteristics.
    This goal is achieved by obtaining coatings by reacting an adduct containing aliphatic and / or cycloaliphatic isocyanate groups with a compound containing an active hydrogen atom, followed by applying the resulting product to the surface to be coated, and curing under the influence of air moisture, as a compound containing an active hydrogen atom, enamine is used with an imino content of 101-164 mg KOH / G.

They can be used individually or & in the form of mixtures, moreover, polyether Huliols, especially when a greater layer thickness is desired, are used in a mixture with one of the two other components.
    As isocyanate, for example, 1,6-hexomethylene diisocyanate, 1-methyl-2, -dirocyanatocyclo- is used. hexane, isophorone diisocyanate, 2, trimethyl-1, 6-diisocyanatohexane, NN -N-tri- (6-isocyanatohexyl) biuret, a reaction product obtained from 3 mol of isophorone diisocyanate and 1 mole of water, as well as the product added by the reaction 3 mol of isophorone diisocyanate and 1 mol of 1, 1,1-trimethylpropane.
    In preparing the composition, conventional plasticizers, diluents, thickeners, thixotropic agents, naponiteli and dyes can be added to the mixture.
    Along with ethics, antioxidants, UV absorbers and biocide agents can be added to the masses.
    At the same time, it is necessary that sufficiently dry materials are used, which, moreover, cannot contain components that are reactive towards isocyanate.
    All components are recycled in a conventional mixer, and care must be taken to ensure that the condition for eliminating moisture is strictly observed.
    The initial composition is cured by first applying it to the surface and being exposed to water or water vapor, respectively, air moisture, or it is first mixed with water and then applied to the surface.
