RAILWAYS FACILITIES
VMP HOLDING has developed the coating systems based on zinc-rich primers to protect the railway constructions, railway freight cars and passenger cars from corrosion.
VMP coating systems are recommended by Russian Railways OJCL for corrosion protection (TI № К-05/06, TI SPI 6/1).
VMP coating systems passed testing and have certificates of the leading industrial institutes and research centers like NII LKP with ОМZ «Victoriya»; Central Scientific and Research Design Institute n.a. Melnikov; OJSC TSNIIS, NICIAMT FSUE "NAMI".
VMP coating systems are included to GOST 9.401-91 "Unified system of corrosion and ageing protection. Paint coatings. General requirements and methods of accelerated tests on resistance to the action of climatic factors", SNIP 2.03.11-85, GOST 12549-2003 "Passenger cars of 1520 mm gauge main-line railways. Painting. Specifications", ТU 5264-853-01393674-07 and TI of applying of high performance coatings under the resistance spot welding in railway freight cars and passenger cars.
