ANTICORROSIVE PRIMING ENAMEL “[UNIPOL]” stamp ATs TU 2312-001-59846005-2003 Field of application Priming enamel [UNIPOL]® stamp ATs - [odnoupakovochnaya] zinc-filled composition, intended for the anticorrosive protection of steel surfaces. Composition contains the highly dispersed powder of zinc, natural rubber- resin bonding agent, organic solvents and contributions of auxiliary substances. Coating is brought for the steel constructions as the priming coating with a thickness of up to 80 m, overlapped for the sake of other paints. Coating does not influence the mechanical properties of the weld, it easily yields to repair and restoration by cleaning and putting the new layer in the place of damage. Coating works in the atmosphere of the industrial medium of that moderated and cold climatic zones. 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. 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). Putting conditions Priming enamel is allowed to bring at an ambient temperature and painted surface from minus of 25o[S] to 35o[S] and relative humidity of air not more than 90%. Method of the putting Priming enamel can be brought by brush, roller, methods of airless and air-stream atomization. Expenditure, the thickness of the coating The recommended thickness of coatings is 70-80 m depending on operating conditions. The theoretical flow rate of priming enamel for one layer 70-80 m composes tentatively 0,20-023 [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 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 70 m, occurs during 7-8 days (t=20oC, [f]=65%). Preparation of priming enamel at the point of the work Before the application to thoroughly mix priming enamel throughout entire volume with the use of a manual or mechanical tool. Priming enamel must be uniform before the color and the consistency. Sediment on the bottom of container is not allowed. Before the putting priming enamel it is necessary to maintain not less than 10 minutes. Of for achievement necessary viscosity is allowed the dilution of priming enamel to 10-15% of the total volume. Xylene or solvent are used as the diluents. However, if necessary, is possible the dilution of priming enamel more than down 15%. Cleaning container, tool Are used solvent, xylene, toluene. Storage Not to heat. To take care from the fire. 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 obtaining negative results during putting of priming enamel, be turned at the point of the detailed consultation down the supplier
