OFP-NV (KRAT) – fire retardant heat-insulating material

1. FIELD OF APPLICATION AND PROPERTIES

Fire retardant heat-insulating composition «OFP-NV (KRAT)» representas a mixture of granulated mineral fiber and non-organic bindingagent.
Coating based on fire retardant heat-insulating compositionOFP-NV (KRAT) is used for increase of fire rating of air ducts, ventilation systems and smoke extraction channels installed in the internal premises.

2. NORMATIVE AND TECHNICAL REQUIREMENTS

Coating based on fire retardant composition "OFP-NV (KRAT)" ensures fire rating of air ducts, ventilation systems andsmoke extraction channels up to 180 minutes (air duct with fire rating EI-180) in accordance with fire safety requirements stated inNPB 239-97 "Air ducts.Method of test on fire resistance" and SNiP 41-01-2003 "Heating, ventilation and air conditioning".

4. SURFACE TREATMENT

Coating should be applied onprimed surface of outside wall of the treated construction.Dust and dirt should be removedby means of wet rags, grease and oil stains can be removed with solvent (solvent 646 is recommended). If application of solvent is not possible use the washing agents.

5. APPLICATION

Application conditions:

Ambient temperature - not less than +5 °;

Relative air humidity - not more than85 %;

Temperature of surface for application of paint should be 3 above condensation point.

Layer of primer solution is to be applied prior to application of fire retardant composition OFP-NV (KRAT). Primer solution should be prepared by means of mixing polymer with water. Concentration of polymer in primer solution makes 25-30 mass%. Application of primer solution is performedby means of high pressure machines of airless sprayingor manually by brush or roller. Fire retardant compund is to be applied on wet layer of primer solution.

Application modes:

Application is performed mechanically by means of gunning machines (ISO-40, ISO Mini Jet). Consumption of compositionfor layer of 10 mm thickness makes 2.5 kg/m2, excl. losses. Required thickness of layer is reached in one pass according to the required fire rating. Final drying time -28 days. If it is necessary toincreasewaterproofing properties or due to design requirements it is allowed to apply enamel of thickness 50-70 micron after preliminary smoothing of surface.

Cleaning of tools:

Wash the tools with water immediately after end of work.

6. OPERATING CONDITIONS AND LIFITIME OF COATING

Operation temperature: from -50 0Ѡto +50 0

Operation of coating in the enclosed premises with relative humidity not more than 90%. Avoiddirect ingress of drop moisture on the coating.

Lifetime of coating is not limited.

7. PACKAGING AND STORING

Fire retardant composition OFP-NV (KRAT)is supplied in bags of25 kg.

Shelf life of fire retardant paint in the packaging of manufacturer -1 year in dry place at temperature above+50.
