Fire-retardant varnish composition "Latik"


LATIK†fire-retardant varnish composition

1. FIELD OF APPLICATION AND PROPERTIES


Fire-retardant varnish composition "LATIK"†constitutes†a two-component†system based†on†combination of fire-retardant†varnish†"Latik" (TU† 2113-038-40366225-02)† and finishing varnish "Zastchita" (TU† 2113-002-58693309-03).
The coating based on fire-retardant varnish composition†"Latik"†is designed for†fire-protection and†prevention of fire spread along wood surface†and wood-based matrials.†The finishing varnish†is used†as part of†the†fire-retardant†varnish composition†to make the coating more protective and decorative,†to improve performace of such properties as water resistance, service life, etc.



2. NORMATIVE AND TECHNICAL REQUIREMENTS

The coating based on fire-retardant varnish "Latik" and finishing varnish "Zastchita" corresponds to group 1 fire-protection rating according to the fire safety requirements set by fire regulations NPB 251-98 "Fire-retardant compounds and substances for wood and wood-based materials. General requirements. Test methods", as well as NPB 244-97 "Construction materials. Decorative-finishing and facing materials. Floor coating materials. Roof water and heat resistant materials. Rire risk indicators".

4. SURFACE TREATMENT


For†application of the coating the surface should be clean and dry. The dust and dirt†shall be removed†by wet cloth. Grease and oil stains shall be removed by a solvent (it is recommended to use solvent No. 646). In case of high humidity,†natural or forced drying†should be applied(by means of†thermal generating units). Primer is recommended to enhance the adhesion†of†fire-retardant†varnish compound†to the surface treated.

5. APPLICATION


Application conditions
ambient temperature—†not less than†+5 °—;
relative air humidity†-†not more than†90 %;
the humidity of the treated surface of the glued wood†should not exceed†12-14% of mass.
Application method
The material should be applied either by†high-pressure airless spraying devices†or manually by means of a brush or roller.
The fire-retardant varnish should be applied in 2†steps with total consumption of not less than 400 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 80-150 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" the tools should be cleaned with water. After application of finishing varnish "Zatschita" 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 based on fire-retardant varnish compound should be used†at temperature of†-50†up 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


fFire-retardant varnish†"Latik" is supplied in†metal pails†of 25 kg, 35 kg.†The storage period of the varnish†in manufacturer's packing in dry conditions†at temperature not lower than +5—†amounts to 6 months.
Finishing varnish "Zatshcita"†is supplied in metal pails†of 10 kg,† 25 kg. The storage period of the varnish†in manufacturer's packing in dry conditions†at temperature not lower than +5— amounts to 12 months.
