Description
Fire-retarding composition constructional RAUM-PROFIE WKR is a pigment suspension in binding material with thermo resistant and thermal insulation additives. Cured surface has low heat conductivity.
Fields of application
The composition is designed to increase the fire resistance of steel structures and structures for industrial and civil purposes, including those operated indoors with non-aggressive or mildly aggressive environments.
Primers such as ГФ-021 (ГОСТ 25129-82 or ТУ 2312-008-20514586-04) should be used to form anticorrosion coating or good adhesion to metal.
Fire -resistance time is 90 min.Instruction for use
Before applying the enamel rust must be removed from the metal surface by any available method (metal brushes, sandpaper or sandblasting). Then the surface is degreased with organic solvents and dried at a temperature close to 20о С for 2-3 hours. The metal is coated with an anticorrosive primer ГФ-021 with a dry layer thickness of at least 50 microns, drying the primer layer at a temperature of 20о С and a humidity of no more than 80%. After drying, flame retardant is applied layer-by-layer with inter-coat drying for 24 hours.
Conditions
Air humidity of no more than 80%.
The surface temperature should be at least 3 0C above the dew point to avoid condensation.
Aplication
| Preparation |
Mix before use. The viscosity may increase when stored for a long time. It is allowed to be thinned up to 3-5% with water to achieve the working viscosity when applied by airless spraying with high-pressure devices. |
