In bridge maintenance management, rust is a factor that shortens the lifespan of structures, and in environments with salt damage or on heavily trafficked routes, the impacts of repair work on construction periods, costs, and traffic regulations are significant challenges. Additionally, when repainting coatings that contain substances like PCBs, methods that involve strict protective measures for dust prevention and safety and environmental considerations are often adopted to remove the coatings. After the removal of the coating, red rust remains, which traditionally required additional substrate adjustments such as blasting or scraping, leading to extended construction periods and increased costs. By using Select Coat N300, the remaining red rust after coating removal can be treated chemically, allowing for the omission of additional substrate adjustment processes. This contributes to a reduction in overall construction time and total costs, as well as improvements in environmental measures and safety. 【Application Scenarios】 - Rust prevention for steel components in bridges - Reduction of construction time in repair work - Decrease in maintenance management costs 【Implementation Effects】 - Suppression of rust progression, contributing to the longevity of bridges - Reduction in construction periods and costs due to shortened construction time - Contribution to reduced environmental impact through the use of water-based paints
