LATIK-KD –fire-retardantvarnish compound

1. FIELD OF APPLICATION AND PROPERTIES


The coating is designed to protect glued wood from fire and fire spread. Finishing varnish "Zatschita" is used as auxiliary material during application. The finishing varnish is used toimprove such operational properties of the coating as wtare-proofness, durability, etc., as well as for decorative purposes.

2. NORMATIVE REQUIREMENTS


The fire-retardant and decorative coatingbased onfire-retardant varnish compound"Latik-KD"complies withfire safety regulationsstated inFire Code (NPB) 244-97 "Construction materials. Decorative, finishing and facing materials. Floor coating materials. Roofwater-and heat resistantmaterials. Fire risk indicators".

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). In case of high humidity,natural or forced dryingshould be applied (by means ofthermal generating units). Primer is recommended to enhance the adhesionoffire-retardantvarnish compoundto the surface treated.

5. APPLICATION

Application conditions
ambient temperature—not less than+5 °;
relative air humidity-not more than85 %;
the humidity of the treated surface of the glued woodshould not exceed12-14% of mass.
Application method
The material should be applied either byhigh-pressure airless spraying devicesor manually by means of a brush or roller.
The fire-retardant varnish should be applied in3-5steps with total consumption of750+50 g/m2. Interlayer drying time amounts to 2-4 hours (depending on the temperature and humidity of the environment). It is not recommended to apply forced drying by means of thermal generating units. Grinding of the surface coated with fire-retardant varnish can be done with fine abbrasive material. Dilution of the fire-retardant varnish is not recommended. The finishing varnish should be applied 2-4 hours after application of the final layer of the fire-retardant varnish. The finishing varnish should be applied in one step with consumption of 150-200 g/m2 depending on the surface type and expected usage conditions. Dilution of the fiishing varnish is not recommended.
The final drying-out period amounts to:
from dust - 20-30 minutes;
before grinding - 1,5-2,0 hours.
Cleaning of tools. After application of fire-retardant varnish "Latik-KD" the tools should be cleaned with water. After application of thefinishing varnish the tools should be cleaned with a solvent (it is recommended to use solvent No. 646).

6. OPERATING CONDITIONS AND LIFE TIME OF THE COATING

The coating should be usedat temperature of-50up to+50 . The coating can be used with air humidity of 100 %.
The life time of the coating is not less than 15 years.


7. PACKING AND STORAGE

The fire-retardant varnishis supplied inmetal pailsof 25 kg, 35 kg.The storage period of the varnishin manufacturer's packing in dry conditionsat temperature not lower than +5Ѡamounts to 6 months.
The finishing varnishis supplied in metal pailsof 10 kg, 25 kg. The storage period of the varnishin manufacturer's packing in dry conditionsat temperature not lower than +5 amounts to 12 months.
