Silane Anticorrosive Coating For Port Sewage
It can effectively prevent the corrosion, loosening, peeling, and mildew of concrete and internal steel structures caused by the erosion of the substrate due to water seepage, sunlight, acid rain, and seawater, and improve the service life of the building.The protected substrate has good water repulsion and retains its original appearance.Alkaline environments such as concrete that has not been poured for a long time will stimulate this reaction and accelerate the formation of a water repellent layer.It is a product recommended by the national anticorrosive specifications of the concrete industry.
Silane anticorrosive coatings for port sewage use the special small molecular structure of silane to penetrate the surface of the concrete and penetrate into the interior of the concrete by a few to more than a dozen millimeters. They are distributed on the inner wall of the concrete pores, and even reach the wall of the small pores. They react chemically with the air and the moisture in the substrate, and polymerize to form a mesh cross-linked structure of silicone polymer hydroxyl groups (similar to silicone bodies), these hydroxyl groups will condense with the substrate and themselves, resulting in glue connection, accumulation, curing and binding on the inner wall and surface of the pores.A tough anticorrosive permeable water repellent layer is formed.
The waterproof treated substrate forms a surface tension much lower than that of water, and produces a capillary reverse air pressure phenomenon, and does not clog the pores, which is both waterproof and maintains the “breathing” of the concrete structure. At the same time, it gives the concrete surface a tougher mechanical properties.
Product features:
◎ Beautiful appearance
Silane anticorrosive coatings for port sewage do not change the original appearance of the building after construction, which can effectively inhibit the phenomenon of darkening and mildew on the surface of the concrete structure due to environmental corrosion such as acid rain and mold and moss, and can maintain a good appearance of the concrete structure for a long time.
◎ Solvent resistance
Silane anticorrosive coatings for port sewage resist various corrosive solvents, such as acid and alkali, chloride ions, carbon dioxide, etc., and protect concrete from the inside out.
◎ Long-term protection
Silane anticorrosive coatings for port sewage have excellent alkali resistance and durability, and have a protective life of more than 20 years.
Construction process:
◎ The surface of the substrate should be cleaned before use, and all treated surfaces should be free of stagnant water, dirt, dust, oil and other pollutants.
◎ Sealed spray guns, rollers or brushes can be used for construction.If you use a brush or roller for construction, you should repeat the application and keep the surface wet for a few minutes; if you use a sealed spray gun, you should continue to spray until the substrate is thoroughly penetrated. When working on the opposite side, it should be sprayed from the bottom to the top, so that the length of the vertical flow reaches 15~20cm.
◎ Before using this product, in order to ensure compatibility and achieve the ideal waterproof effect, each surface to be treated should be tested for application.
Scope of application:
It is widely used in all kinds of reinforced concrete structures, such as commercial buildings (internal and external walls of buildings, roofing and ground), parking lots, garages, warehouses and cold storage, swimming pools, expressways, bridge structures, expressways, ports and docks, marine engineering, etc., especially suitable for high-grade concrete structures used in harsh environments, roads, overpasses, telephone poles eroded by salt spray and ice salt, sewage treatment ponds in sewage treatment plants, landfills, plateau areas with great temperature differences, etc.
