Anticorrosive epoxy primer with rust - iron red; Chongqing iron red epoxy primer consists of an epoxy resin, red iron oxide pigments and new anti-rust, anti-corrosion additives, chemical rust, mixed solvents to polyamine synthesis thing as curing agent, prepared from the two-component products. Performance is a room temperature curing anticorrosive shop primer, fast drying, excellent film physical and mechanical properties, with the end of all types, topcoats can be painted with rust. Because no metal zinc and other substances, thereby reducing the dangers of welding produce gas on the human body. Use for steel, artificial rust and rust as rust primer, dry film thickness of 25 microns, the effective protection of the steel for six months. A ratio of iron red color component (paint): B (curing agent) = 20: 1 or 10: 1 (weight ratio), Chongqing Iron red primer construction surface cleaning cleanliness rating that is representative of international standards There are two types: one is the United States 85 years to develop "SSPC-"; the second is 76 years in Sweden developed "Sa-", which is divided into four grades were Sa1, Sa2, Sa2.5, Sa3, for international the usual common standards, as detailed below: Sa1 level - the equivalent of US SSPC-SP7 class. Using the general simple manual brushing, emery cloth grinding method, which is the lowest of the four cleanliness moderate level of protection of the coating is only slightly better than the workpiece processing is not employed. Sa1 level processing technology standards: the surface should not be visible oil, grease, residual oxide, rust, and paint residues and other contaminants. Sa1 level also called manual brushing cleanup levels. (Or cleaning level) Sa2 level - the equivalent of US SSPC-SP6 class. Using blast cleaning method, which is the lowest level of sandblasting, that general requirement, but for protection than manual brushing coating to improve the lot of cleanup. Sa2 level technical standard treatment: the surface should not be visible greasy, dirt, scale, rust scale, paint, oxides, corrosion, and other foreign matter (except for defects), but the defect is limited to no more than per square meter surface 33%, which may include a slight shadow; because a small amount of mild decolorization defects, corrosion caused; scale and paint defects. If the original surface of the workpiece dents, rust and paint the minor will be left in the bottom of the dent. Sa2 grade, also known as commodity cleanup level (or industrial). Sa2.5 level - is commonly used in the industry and can be used as the acceptance level of technical requirements and standards. Sa2.5 level also called near white cleanup level (near white or a white level). Sa2.5 level technical standard treatment: the first half with Sa2 require the same, but the defect is limited to no more than 5% per square meter surface, which may include a slight shadow; because a small amount of mild decolorization defects, corrosion caused; scale and paint defects . Sa3 level - level equivalent to the US SSPC-SP5 level, is the highest level of industrially processed, also called white cleanup level (or white level). Sa3 level technical standard treatment: the same but the 5% level Sa2.5 shadows, defects, corrosion and so had to exist.
