ANTICORROSIVE PRIMING ENAMEL “[UNIPOL]” stamp B TU 2312-001-59846005-2003 Field of application Antifouling paint priming enamel [UNIPOL]® stamp B is intended for the anticorrosive protection of steel (including zinc-coated), concrete and ferroconcrete constructions due to the conditions of the moderate and cold climate for the creation [ogranichenno] of weatherproof anticorrosive coatings. The waterproof and chemically resistant anticorrosive covering, which maintains for a long time the action of dry salts and alkalis, their concentrated solutions, is formed. Surface preparation of the concrete Concrete surface must be flat, clean and dry. According to SNIP (Construction norms and regulations) 3.04.03 the humidity of concrete is allowed not more than 4%. The surface of concrete must be evened and removed based on it lime milk, upper fragile layer of concrete and remainders of old coatings. After the surface treatment it is necessary to remove dust, sand, swarf and other pollution from the zone of painting. The presence on the concrete of the spots of the machine oil or other chemical compositions is inadmissible. Preparation of the steel surface From welded joints to clean the welding slag (flux) and the layers of slag. By grinding to remove incisions, burrs, welding drops, to round off sharp edges, angles, teeth, the welds. For the removal of the interfering layers it is possible to use scrapers, chisels. Work should be performed in such a way as not to disrupt weld strength. Beyond the surface must be absent the lubricant, the marking paint and other substances (mineral pollution, water-soluble salts), which influence the quality of surface preparation. If necessary, before conducting of abrasive- jet cleaning, for the removal of organic pollution it is necessary to use a solvent (mineral spirits according to GOST 3134). Degreasing to produce down degree of 1 (ALL-UNION STATE STAN. 9.402). The metallic surface of the constructions, which are subject down protection, must be cleaned down the degree of cleaning S[a] 2,5 (ISO 8501-1) or down the degree of cleaning 2 (ALL-UNION STATE STAN. 9.402). With the fulfillment of the anticorrosive protection of noncritical constructions is permissible the use of cleaning metallic surface down the degree St of 3 (ISO 8501-1). Before the dyeing the surface must be dry and clean. Preparation of the zinc-coated surface The emergent beyond the zinc-coated surface white rust before the painting must be removed by washing under the pressure by hydroabrasive working or the careful grinding. Surface “to [promatirovat]”. Beyond the surface must be absent the lubricant, the marking paint and other substances, which influence the quality of surface preparation. Surface must be purified of dust and degreased (mineral spirits according to GOST of 3134 small surfaces and by hot vapor of large surfaces (ISO 12944-4). Before the dyeing the surface must be dry and clean. Putting conditions Antifouling paint priming enamel is allowed to bring at an ambient temperature and painted surface from minus of 25o[S] to 35o[S] and high relative humidity of air. The surface temperature must be higher than the dewpoint not less than as far as 3o[S]. It is forbidden to tincture surfaces covered for the sake of hoarfrost and ice crust. Method of the putting Antifouling paint priming enamel [UNIPOL] can be brought by brush, by roller, by the methods of airless and air-stream atomization. Expenditure, the thickness of the coating The recommended thickness of anticorrosive coatings is 180-400 m depending on operating conditions. The theoretical flow rate of the antifouling paint of priming enamel for one layer 100 m composes tentatively 0,22 [kg]/[m]2. Practical expenditure depends on many factors: the equipment used, the degree of preparation and complexity (form) of surface, weather conditions, qualification of personnel and so forth For the grounding of concrete surface use the diluted anticorrosive enamel [SBE]-111 “OF [UNIPOL]” ® the stamp B, obtained during the addition of solvent from calculation by 1:1 about the volume or “[UNIPOL]- waterproofing” about the agreement for the sake of the producer. Ambient temperature, °[S] Time, ch -25 1 -15 2 -5 2 0 1 +20 to +35 less than 1 The time of interlamination drying indicated depends on number of the factors: the diluent used, the air circulation, ambient temperature, thicknesses film and the like and considerably it decreases with grow prettier ventilation, also, before open air. The complete set of the physicomechanical properties of the coating with a thickness of 180 m, occurs during 7-8 days (t=20oC, [f]=65%). Preparation of the antifouling paint of priming enamel at the point of the work Before the application antifouling paint priming enamel to thoroughly mix throughout entire volume with the use of a manual or mechanical tool. The obtained paint must be uniform before the color and the consistency. Sediment on the bottom of container is not allowed. Before the putting anticorrosive composition, priming enamel [UNIPOL] it is necessary to maintain not less than 10 minutes. Of for achievement necessary viscosity is allowed the dilution of anticorrosive composition, priming enamel to 10-15% of the total volume. Xylene or solvent are used as the diluents. However, if necessary, is possible dilution more than down 15%. Cleaning container, tool Are used solvent, xylene, toluene. Storage Not to heat. To take care from the fire. Anticorrosive composition to store before the solidly closed container, protecting from the action of heat, the straight lines of the solar of rays and moisture. Guarantee period of storage before the hermetically sealed container of manufacturing plant - six months based on the day of production. For obtaining the additional information for the sake of the putting, the quality of surface preparation or in the case of obtaining the negative results during putting of priming enamel, to be turned at the point of the detailed consultation down the supplier
