NK Rust Stabilization Anti-Corrosion Method for the Maintenance and Repair of Bridges and Steel Structures NETIS
Inorganic coating: A long-lasting repainting method with three types of surface preparation. Solvent-free epoxy resin-based rust stabilization paint + inorganic paint.
NETIS Registration Number: SK-100009-VR (Promotional Technology) (VR) The surface preparation involves three types of grinding, and any rust that cannot be removed is stabilized with a solvent-free epoxy resin-based rust stabilization paint: NK-100-E. It is then protected with a durable coating method using an inorganic paint: Seal Coat 007M, which excels in electrical insulation and weather resistance. This method reduces noise, dust, and industrial waste generated during surface preparation. The paint system uses safe materials that do not contain harmful heavy metals. Since NK-100E is solvent-free, it does not compromise the active film. It has high gas barrier properties, preventing the intrusion of water and oxygen, which are factors that cause rust. Seal Coat 007M consists of two-thirds inorganic components, resulting in minimal degradation of the coating film due to ultraviolet rays (chalking) and providing superior weather resistance compared to fluoropolymer paints. The two-layer application of inorganic paint protects the primer paint, creating a long-lasting painting system. It is also possible to use the solvent-free inorganic paint Seal Coat 007U as a topcoat. This repainting method contributes to the maintenance and repair of bridges and steel structures where blasting is difficult, enhancing long-term durability. It is also suitable for repainting systems that contain harmful substances, lead and lead compounds, chromium and chromium compounds, and PCBs.

Company information
The NK rust stabilization anti-corrosion method involves three types of surface preparation, with a primer using a solvent-free epoxy resin-based rust stabilization paint, and an intermediate and top coat using inorganic paint. The primer, NK-100E, is solvent-free and has strong adhesion and high gas barrier properties, making it a safe paint that does not compromise the active film. The film wear rate of the intermediate and top coat, Seal Coat 007M, is slower than that of fluorine, ensuring a film thickness that is twice as thick. T&C Anti-Corrosion for salt damage is a combined type of impregnation material that combines silicate-based impregnants and silicone-based water repellents. It is a hybrid type that possesses the advantages of both types of impregnants, effectively preventing the intrusion of carbon dioxide and water, making it particularly effective in salt damage environments. In general environments, T&C Anti-Corrosion is utilized. Nano Coat Clear is a breathable glass paint suitable for protecting exposed concrete, preserving the texture of the exposed concrete. The method using inorganic paint achieves long-term durability for structures such as social infrastructure and contributes to the reduction of life cycle costs (LLC).
