PLAMCOR-4 fire-protective plaster for steel structures (VMP)
Dry mix based on Portland cement and expanded vermiculite for structural fire protection of steel structures indoors.

A two-component polyurethane enamel that completes the waterproofing system for bridge superstructure slabs IZOLEP-WP-01 + IZOLEP-WP-11 + IZOLEP-WP-33. It is applied over the IZOLEP-WP-11 membrane not earlier than 24 h and not later than 3 days at 20 °C; the coating is resistant to weathering, including ultraviolet, and serves as a protective and decorative finish coat. The enamel gives a semi-gloss grey or light grey surface and is applied by airless spray without thinning, by brush or by roller.
