PAINT FIRE-RETARDANT DISTENDING ITSELF “[INTUMESTERM]” TU 2316-002-59846005-2003 “[INTUMESTERM] paint” is tested down the fire-retardant effectiveness before the specialized organization, which has the appropriate accreditation, with the formulation of the certificate of fire safety. Limit of fire resistance 1 hour. Paint is the distending itself closegrained fire-retardant cover system for the carrying steel constructions. Surface preparation The surface of the metal structures before the application of coating must be preliminary purified of mud, rust, slag and old paint. Cleaning can be produced by the manual or mechanized method. Fatty pollution beyond the surface it is necessary to remove by organic solvents or by the washing compositions throughout the beginning of mechanical cleaning in accordance with ALL-UNION STATE STAN. 9.402. After cleaning of metal structures the surface must be protected by ground [GF]-021 with a thickness of up to 0,05 mm. Method of application Before the application fire-retardant paint must be thoroughly mixed throughout entire volume during 5 minutes in a mechanized manner or during 15 minutes by hand, after which they maintain before the putting around the disappearance of bubbles not less than 10 minutes. For the best of the hiding power of surface and achievement of the necessary (working) viscosity it is necessary to add the solvent before the direct application of material before a quantity to 10% of the total volume. Sediment on the bottom of container is not allowed. Diluents: toluene, xylene. The same solvents can be used for the washing of tool, container and spots. Work on fire protection of metal structures is conducted before the following order: paint down the surface is brought in layers by airless dispersion either by pneumatic spraying, by painter's brush or by roller. Each freshly applied layer must be dried and that following is brought after drying of previous down degree of 3; With a change in the ambient temperature the time of drying can increase or be reduced. Putting conditions Temperature of ambient air during putting of paint beyond the surface, which is subject down protection, from minus of 25°[S] to plus of 35°[S], relative humidity to 100%. The application of coating beyond the steel columns of the double-T profile cross section of № 20 (given thickness of metal 3,4 mm) for the sake of the thickness not of less than 1,75 mm ensures fire-retardant effectiveness not less than 1 hour, which on [NPB] 236-97 corresponds to the 3rd group of effectiveness. The thickness of coating is measured with the aid of the thickness gauge of the type Of minitest 2100 or by similar with an error of measurement not more than 2%. Expenditure, the thickness of the coating The expenditure of paint during putting of one layer composes 400-600 [g]/[m]2. For obtaining the layer of coating 1,75 mm it is necessary to apply not less 3rd layers. The expenditure of composition in this case will compose 2,6 [kg]/[m]2. Precautionary measures With conducting of internal work, and after their end thoroughly to also air accomodation. To use individual protective means. Storage, the guarantee Not to heat. To take care from the fire. Composition to store before the solidly closed container, protecting from the action of heat and straight solar rays. Guarantee period of storage - 12 months based on the day of production before the hermetically sealed metallic container. Technical specifications № in sequence Designation of the index Norma 1.
