KL-1V –Fire-retardant paint for protection of electric cables

1. FIELD OF APPLICATION AND PROPERTIES


Fire-retardant paint "KL-1V"is a suspension made of antipyrite,gas and foam formingfillerswith non-organicadditives in organic emulsion.
Under high temperaturethe coating formsfoamy layer,preventing fire from penetrating intothe insulating jacket of the cable.
The coating based on fire-retardantpaint "KL-1V" is designed to protect cables from inflammation and fire spread, used in open air and underagressive conditions.

2. NORMATIVE AND TECHNICAL REQUIREMENTS


"KL-1V" Fire-retardant paintfor electric cablescorresponds tofire-safety requirements,set byFire Regulations 238-97 "Fire retardantcable coatings.Generaltechnical requirements andtest methods"preventing flame spread.

3. TECHNICAL PROPERTIES


Density, kg/m3,not less than 1300+100
Content of non-volatile matters, % mass.70±5
Colour light to dark brown

Theoretical consumption andrecommended thickness of the film

4. SURFACE TREATMENT

Forapplication of the coating the surface should be clean and dry. The dust and dirtshould be removedby wet cloth. Grease and oil stains should be removed by a solvent (it is recommended to use solvent No. 646). If a solvent is impermissible, detergent solutions can be used. Cable marks should not be painted. For this purpose they should be protected by adhesive tape.

5. APPLICATION


Application conditions
Ambient temperature -not less than+5 °;
Relative air humidity-not more than85 %;
Application method
The material should be applied either byhigh-pressure airless spraying deviceswith plunger pump («WAGNER HC 55 E», «GRACO») or manually by means of a brush or roller. The coating should be applied in 2-3 layers. The first layer (priming) should be applied with consumption of 170-200 g/m2. The priming layer should increase the adhesion of the paint to the surface treated. The paint can be diluted with water (up to 5-10% of the initial mass) as the priming layer. In this case the paint should be thoroughly mixed with electric mixer equipped with turbulent-type cap for 3-5 minutes. The subsequent layers should be applied not earlier than 4 hours after application of the priming layer with consumption of up to 600 g/m2 unless the required final thickness of the layer is reached. The interlayer exposition should amount to not less than 6-8 hours.
The final drying-out period amounts to 2 days.
Cleaning of tools
Tools should be washed immediately after application.

6. OPERATING CONDITIONS AND LIFE TIME OF THE COATING

The coating is designed for operation in open air and under agressive conditions.
Operational temperature: -40°Ѡup to+50°
The operation period of the coatingis not less than25 years.

7. PACKINGAND STORAGE

Fire-retardant paint "KL-1V" is supplied inmetal 25 kg pails.
The storage periodof the paintin dry conditionsunder temperaturenot less than+5 °Ѡand not higher than +40° in manufacturer's packing amounts to 1 year.
