Full Product Information:Type: Sacrificial corrosion primer is a suspension of zinc powder in a solution of epoxy resin with the addition of special additives, solvents. It delivered in the form of two components - semi-finished primer and hardener E-45. Advantages: primer forms a coating with excellent adhesion to the substrate, resistance to abrasion and mechanical stress. The tread primer protection mechanism ensures durability, water resistance and anti-corrosion paint complex. The content of zinc in the dried coating at least 90%. Surface preparation: Before priming the metal surface should be thoroughly cleaned of rust, scale and other impurities. The most thoroughly be cleaned surface zone of welds of up to 3 cm from the flux residues, and dross alkaline oxides formed during welding. Weld spatter, chips, deepening, undercuts or sharp projections from the manual welding, as well as the rough edges, made by flame cutting, must be removed or smoothed power tool. Next, the surface is degreased before the first degree (GOST 9.402) and treated by shot or sand blasting treatment to the extent of two oxides (GOST 9.402) and a roughness Rz of 20 to 40 microns (GOST 2789). After grit blasting or the coating thickness must be increased to account for the degree of surface roughness Ra. Increasing the thickness of the coating can improve barrier properties. The color of the surface of the produce, not later than 4 hours after surface preparation. To eliminate the condensation temperature of the painted surface must be above the dew point temperature at least 3 ° C. The ambient temperature and the primer should not be below 5 ° C and relative humidity - less than 80%. Recommendations on Application: The primer is applied by pneumatic and airless spray or brush in 1 - 2 coats. Before applying the primer cake mix thoroughly. Then enter the E-45 hardener in the ratio: 100 mh semi-priming -.. 5 m. H. The hardener mix, let stand for 30 minutes, depending on the application method, RTSL diluted with solvent in an amount up to 12% by weight of the primer and filtered. Drying time single-layer coating - no less than 3 hours at a temperature (20 ± 2) ° C and a relative humidity of 65%. At lower temperatures, and high humidity drying time increases. Drying the coating is allowed to at (120 ± 2) ° C - 30 minutes. The thickness of the dried coating at least a single layer of 60 microns. In the case of applications for metal primer paint, designed for electric welding, layer thickness in the weld areas must not exceed 20 microns. In welds, end edges and hard to reach areas before painting is done brushing primer in the form of "strip layer." The time prior to the application of coating materials and to transport painted primer product should be not less than 24 hours. In the process of applying the first coat should be periodically stir in order to avoid the deposition of zinc powder. Shelf life of the primer at least 12 hours at a temperature of (20 ± 2) ° C if stored in a tightly closed container. Primer consumption per single-layer coating is 270 - 340 g / m? without taking into account the complexity of the painted surface, application method, staff development and other factors. semi-finished primer density is 2.9 - 3.1 g / cm ?. It allowed the formation of sludge and delamination during storage primer semi-finished product, if after thorough mixing and addition of hardener E-45 primer is not coagulated and keeps painting and protective properties. Precautions: When carrying out painting works, as well as after their closure should be thoroughly aired. To protect your hands to use rubber gloves. Storage: Store cake mix primer in a tightly closed container, protected from moisture and direct sunlight. Keep away from fire!
