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 period, costs, and traffic regulations are challenges. Additionally, when repainting coatings that contain substances like PCBs, strict precautions are taken to prevent scattering and ensure safety and environmental measures, leading to the adoption of methods that involve removing the coating. After the coating is removed, red rust remains, which traditionally requires additional surface preparation such as blasting or scraping, resulting in 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 surface preparation processes. This contributes to a reduction in overall construction time and total costs, as well as improvements in environmental measures and safety. [Usage 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 of construction period and costs due to shortened construction time - Contribution to reduced environmental impact through the use of water-based paints

In the automotive maintenance industry, proper treatment and repair of rust are essential to maintain vehicle safety and aesthetics. In particular, rust caused by external factors such as aging and de-icing agents progresses quickly if left untreated, leading to reduced vehicle lifespan and the need for re-repair. Traditional rust prevention methods often require rust removal or parts replacement, which can be challenging in areas where the thickness of the steel plate cannot be adequately secured. Select Coat N300 (Rust Change) is a rust-conversion type paint that can be applied directly over rust, allowing for rust treatment without excessive grinding of the steel plate, contributing to the simplification of the repair process and improved work efficiency. It has a proven track record in high-frequency rust occurrence sites, such as repairs for large vehicles in snowy regions, leading to reduced risk of recurrence and extended lifespan of vehicle outer panels. 【Usage Scenarios】 - Rust repair for vehicle bodies, frames, mufflers, etc. - When rust treatment is desired without parts replacement - When aiming to simplify the repair process and reduce work time 【Benefits of Implementation】 - Reduction in repair work time - Cost reduction through decreased parts replacement and labor - Suppression of recurrence through rust conversion and extension of vehicle lifespan

In tunnel maintenance, rust on rebar can cause concrete spalling and cross-sectional defects, leading to a decrease in the durability of structures. Particularly inside tunnels, issues arise from work restrictions, extended construction periods, and increased costs associated with repair work. In spalling repairs, it is necessary to treat the rust on exposed rebar after chipping, which traditionally required a lot of effort and time for scraping work. By using Select Coat N300, the remaining red rust on exposed rebar can be chemically treated and converted into a stable state. This allows for the omission of excessive rust removal work, contributing to the rationalization of the repair process, shortening of construction periods, and reduction of total costs. 【Application Scenarios】 - Spalling repair of rebar inside tunnels - Rust treatment of rebar before cement and mortar placement - Reduction of work burden in repair construction 【Implementation Effects】 - Suppresses the progression of rust on rebar, contributing to improved durability - Shortening of construction processes leads to reduced construction periods and costs - Adoption of water-based paint contributes to safety and reduced environmental impact

In railway facilities, rust on rails and metal components can progress rapidly due to the usage environment and storage conditions, leading to increased replacement frequency and maintenance costs. Select Coat N300 (Rust Change) is a water-based rust converter that can be used alone as a simple rust prevention and prolongation measure during rail repairs and storage. By chemically stabilizing exposed red rust, it allows for easy repairs without the need for excessive rust removal work. Additionally, it demonstrates good adhesion not only to red rust areas but also to non-ferrous metals such as zinc plating, making it applicable to partially rusted catenary poles and signal equipment boxes. Even in components where red rust and non-corroded areas coexist, stable corrosion prevention measures can be implemented through integrated application. 【Usage Scenarios】 - Simple rust prevention and prolongation measures during rail repairs and storage - Maintenance and repair of railway bridges and overpasses - Rust prevention measures for partially rusted catenary poles (zinc-plated components) - Corrosion prevention for metal equipment such as signal equipment boxes 【Implementation Effects】 - Stabilizes red rust and suppresses re-corrosion - Contributes to the prolongation of rails and components through simple rust prevention - Improves work efficiency under time constraints, such as nighttime construction - Allows for integrated application regardless of ferrous or non-ferrous components
