Fire protection material description
Fire protection intumescent material is the solvent-borne suspension of pigments and special-purpose fillers in acrylic polymer solution. Swells when heated (about +250 °С) and forms a protective layer from coked cellular material with low conductivity which prevents heating of steel structures.
The coating is non-toxic, emits no harmful substances when heated, does not form toxic compounds on contact with other substances. It is delivered ready to use in metal containers with tightfitting lids.
OGRAX-SK-1 was certified for compliance with the Technical Regulations of Fire Safety Requirements (Federal Law №123 dated 22 July 2008), test method as per GOST R 53295-2009.

Application method
Mix thoroughly prior to application.
Use airless spray to apply layer by layer, or apply with a roller or a brush.
The air temperature during the application should be between +5°C and +50°C.
Surface to be protected should be dry, free from dirt, rust, old paint, etc. The material applied to primed surface.
Use personal protective equipment. In case of contact with eyes rinse them thoroughly with water.
Drying period between layers is 2-3 hours, complete drying in 10-15 days.

Storage and operation conditions
Storage and transportation in tightly closed containers at temperature from -60 °C to +60°C
