Fmp coatings for bridge engineering
THE BEST RATIO OF THE PRICE, QUALITY AND WORKING LIFE
MATERIALS SUPPLY RESPONSIVENESS RECOMMENDATIONS, TECHNOLOGICAL SUPPORT
Use of coating systems of FMP is especially of current importance for protection of extra responsibility objects, to which bridges, gantries, overpasses concern.
Not occasionally long cooperation connects FMP with bridge engineering field. In this field the enterprise is the principal domestic supplier for zinc-rich primers for more than 15 years and recently for complex polyurethane coating systems.
For the present moment more than 200 thousand tons of metalwares, motor-car, railway, foot-bridges and pedestrian crossings and subways are protected from corrosion by FMP coatings.
Application experience
Examples of transportation building objects, metalworks of which are protected by FMP coatings:
- Numerous gantries and overpasses concerns, located on Moscow encircling highway;
- The bridge crossing Moscow-river near “Christ the Saviour temple” – “Patriarchal”, Moscow;
- Projected bridge crossing Volga river, Ulyanovsk;
- Guyed highway bridge crossing Ob river, Surgut;
- Railway bridge crossing Irtish river, Tobolsk;
- Bridge crossing Ob river on the north bypass Novosibirsk;
- Ushakov flyover, Saint-Petersburg;
- Bridge Ì-2 crossing Ishim river, Astana;

Branch certification, tests
FMP coating systems have passed full branch certification and introduced into all basic normative documents defining anticorrosion protection of artificial transport constructions:
- Construction regulations 001-2006 “Anticorrosion bridge metal constructions protection by tinting”, Limited company “Group of companies “Transstroy”;
- “Technological guidings for coating of metalworks of exploited railway bridges”, Communication Lines Ministry of the Russian Federation;
- “Guiding for metalworks anticorrosion protection and for repair of lacquer coating of exploited highway bridges metal spans”, Ministry of Transport of the Russian Federation - State deputy road economy (ROSAVTODOR);
- FMP coating systems are introduced into addition to Construction regulations 2.03.11-85 “Anticorrosion building constructions protection” and recommended for application by “Gosstroy”, Russia.
FMP coatings has been successfully tested and have findings of key branch institutes and research centers, including: All-Russian Research Institute for Construction and Operation of Pipelines; Melnikov Central Research and Project Institute of Building Constructions; All-Russian Research Institute for Rail Transportation; Research Institute for Lacquer Coatings (Hotkovo); State Unitary Enterprise – Research Center for Testing and Refining Automotive Vehicles.
FMP coating systems for bridge constructions protection
Bridge metalworks are maintained in complex conditions causing accelerated corrosion of steel. They are influenced with atmospheric precipitates, solar radiation, temperature variations, aggressive gases, alternating mechanical loadings. At the same time the technical condition of these complex engineering constructions has strategic importance for economy and safety of the country, and their design condition architectural shape of cities and regions.
Therefore the choice of a reliable way of bridge constructions anticorrosion protection at is one of the major problems during their construction and repair. It is conventional, that the most reliable and accessible way of anticorrosion protection of metal is application of paint-and-lacquer coating systems on the basis of zinc-rich primers.
FMP coating systems meet international requirements, providing long-term, more than 10 - 15 years, anticorrosion protection of bridge construction metalworks. They consist of 2 or 3 layers of paint-and-lacquer materials with different protection mechanisms, each of which carries out its function (see the fig.).
Standard systems are shown in the table.
Zinc-rich primers ZINOTAN, ZFES with high (more than 86 %) content of zinc powder, realizing rated (cathode) steel protection, in much the same as traditional zinc coatings, therefore their application has been named of “cold” galvanizing technology.
The next layers of system - intermediate and covering, operate on the barrier mechanism, preventing penetration of hostile environment to metal.
Enamel POLITON-UR, compositions ALUMOTAN and others are applied for them. High barrier properties of these materials are provided owing to use of effective anticorrosive components as polyurethane resins and pigments of the flaky structure.
Combined system scheme of the protective coating
Coating materials function as decorative as well. Enamel is coloured any kind of the color variety represented in catalogue RAL. The enamel POLITON-UR (UV) is ultra-violet radiation resistant, perfectly retaining coating color at application. Alumo-rich coating ALUMOTAN meets up-to-date trends of “silver” bridges consruction. Thus, owing to FMP coatings all architects’ plans.
Materials of FMP production are technological, plain and easy-to-use. They are applied by means of airless or pneumatic spraying with application of standard equipment in plant and field environments. Materials are applied in a wide range of the Russian climatic conditions, at negative temperatures and high humidity.
Polyurethane materials ZINOTAN, ALUMOTAN and POLITON-UR, cured by air moisture, have perfectly proved at painting, especially at a construction site. Composition ZFES is one of the most quick-drying primers, widely applied in bridge construction.
Friction joints protection.
Use of undercoats ZFES and ZINOTAN for protection of frictional joints of bridge metalworks at makers will allow avoiding labour-consuming abrasive blasting preparation of contact surfaces at installation on a building site.
Concrete constructions protection.
FMP polyurethane coating systems are applied not only for metal, but also for concrete constructions. Here special penetrating primer FERROTAN-PRO, cure by air moisture is applied as prime coating. The same primer is also recommended for metalworks repair, when surface abrasive blasting is impossible.
