Forpol-ZhD — spray-applied polyurea-urethane mastic for bridges and tunnels
Anticorrosive and waterproofing mastic for railway bridges, tunnels and platforms, elongation more than 100 %.

The silver paint BT-177 from AO “KRONOS SPb” consists of BT-577 varnish and aluminium powder, which are mixed immediately before use. The paint is applied by spraying or brush on ferrous metals and aluminium alloys — without a primer or over a primer — for structures and products in the atmosphere of temperate and cold climates, under a canopy and indoors. The coating is resistant to water and mineral salt solutions and withstands changes from −50 to +60 °C; natural or hot drying is permitted.
