Industrial floors must resist a series of factors like heavy weights and traffic as well as high mechanical stress and different chemicals. In short, they must be very tough. Every day, they are on the job and are literally the "foundation" of all kinds of businesses. One example where an industrial floor needs to stand up to extreme pressure and heavy use are maintenance centers for railway cars, and as the Brateevo depot located in the Southeast of Russia‘s capital Moscow. The new multifunctional complex is designed to carry out, maintenance, repairs, and the overhaul of underground railway cars from all lines of the Moscow Metro. The Moscow metro system is the fourth longest in the world and the busiest one in Europe with 2.5 billion passengers a year. The Brateevo depot also includes a number of infrastructure facilities for servicing the important Zamoskvoretskaya line (Line 2), crossing Moscow on a length of 42.8 kilometers (26.6 miles) in a north–south direction. The large capacity of the depot allows it to overhaul 300 cars annually, with compare to a medium complexity to another 500.
During the depot‘s construction, choosing the right flooring played a very important role. For the best performance on concrete, a high-quality self-leveling epoxy flooring system was chosen. For the formulation of a suitable floor coating, Ancamine® curing agents from Evonik‘s business line Crosslinkers were the perfect choice. Why? Because floor coating systems for industrial facilities based on Ancamine® 2605 and Ancamine® 2519 help to ensure that the flooring is always well protected, even under harsh conditions: Both products offer optimum prevention against chemical substances, are resistant to dust and water spotting, improve wear resistance and appearance with a beautiful finish, and additionally, exhibit fast drying under low (room) temperature conditions for a quicker turnaround of application. The products also score with low viscosity. In the case of the Brateevo depot, Ancamine® 2605 was used for the formulation of the primer and Ancamine® 2519 for the formulation of the top coat. For even better results, Ancamine® K54 was additionally used as an activator for the curing agent in the top coat.
