On May 1, 2008 ZAO morning updated its stand on the constant-current exhibition "LenNIIProekt" in St. Petersburg, where available, and fire-retardant coatings. At the exhibition you can see in practice all the advantages fire-retardant paints and varnishes from the company. And speaking theoretically about fire retardant paint and varnish, flame-retarded, then we can draw the following conclusions: Fireproof paint – this is one of the most modern flame retardants, which is able to provide quality fire protection on the cable (in case of fire do not allow the flame to spread along the cables), metal (metal retard warming in the fire and keep the device in within the required time), timber (preventing the spread of flames on the wooden roof and wall elements to form a fire-resistant layer, which does not allow the wood to ignite.) Fire retardant paint to create surface insulation screens that provide exposure of high temperatures and impacts of fire. Fire retardant paint is part of the thin-flame retardant materials, the thickness of an average of only 1 mm. and this means that the application of fire retardant coating does not change the shape of machined structure.

The advantage of fire-retardant paint is the method of application. In contrast, flame retardants, for application that required overall plastering machines, fire retardant paint may be applied by hand or spray gun, such as a roller or brush. Fire retardant paints can be divided into two groups: nevspuchivayuschiesya (at heating does not increase the thickness of the layer on the surface of the object) and swelling (considered the most effective, because at higher temperatures significantly increases the thickness of the layer – in 10-40, forming a foam layer, heat-insulating). Fire retardant paints – used for protective and decorative treatment of different surfaces: wood (three-layer varnish coating consumption by at least 265 g/m2 provides transfer of wood in a group of inflammable material), concrete, asbestos-cement, brick and stucco, operated indoors or in weather conditions, which is a big advantage fire-retardant paint. Fire retardant paints a solution Polymethylsilicone resins with the introduction of functional additives, is produced ready for use. Drawing on the wood surface by brush, roller or pnevmoraspyleniem with intermediate drying between layers 1 hour at 18-22 C. The final drying of the last layer – 2 hours. Fire retardant properties appear as the volatilization of the solvent (ie, within 20 days After applying a layer of varnish on the surface to be protected. When applying the varnish must comply with fire safety.
