Use as a film-forming uralkidov in formulations parquet varnishes not only accelerates the process of drying, but also leads to a significant improve the performance of the above. EXL Service gathered all the information. Uralkidnye varnishes, perhaps, the most commonly used in the West to protect the flooring and the labels in most cases they are referred to as polyurethane varnish. They are important advantage is the relatively low price, slightly differs from the price of alkyd paints. Get more background information with materials from CBRE. It should be noted, however, that, according to data cited in the article by Mr. WW Kudryavtseva (magazine 'Paint materials and their application ', 2000, N5, P.7-11), domestic uralkidny lacquer AU-271' Polyuria 'production Circassian HPO inferior to foreign analogues by the drying time, color, and abrasion resistance, which the author explains the lack of otrabotannostyu synthesis process and the lack of uralkida varnish formulation of so-called 'sliding additives'. The most high-performance, primarily for water resistance and abrasion resistance of coatings polyurethane coatings have – as a single component, moisture curing by air and two-component (first component-hydroxy polyester, the second – the isocyanate prepolymer), produced by many foreign firms.

In our country we have been able to identify only two firms producing such coatings, one in Moscow (000 'polymers'), which produces polyurethane varnish hardwood under the brands 'Gala' and 'Sport' on imported raw materials, the other in Dzerzhinsk, Nizhny Novgorod region. (000 'Ekopol'), which produces two-component polyurethane varnish UR-5-66 on the basis of domestic raw materials. However, both firms produce a polyurethane varnish parquet only in small quantities and can not ensure that the needs of the market. It should be noted that even in the sixties in the laboratory of AA Blagonravova State Research and Design Institute of the paint industry GIPI LCP was Designed and produced in pilot-industrial scale, a great one-part polyurethane varnish parquet SD-19, received the highest scores of consumers. Alas, unfortunately, at present, this varnish is not available.
