Monolit OM fire-protective plaster for steel structures (KrilaK)
Dry mix of hydraulic binder for fire protection of steel structures indoors and outdoors, performance up to 240 min.

KrilaK produces Monolit M1, a dry mix of mineral binder with heat-resistant fillers, as the replacement for the Eskalibur compound. The fire resistance rating of steel structures is R up to 240, fire protection performance group 1 per NPB 236-97, including for hydrocarbon fire. It is suitable for unheated buildings and structures and is applied over primer with robotic equipment MIS-800, T-103, AK-800, SO-150 or Putzmeister. The service life is at least 50 years.
