For those troubled by rust on roofs! A rust-proof primer that can also reduce the cost of scraping work.
Protect steel structures and metal components from rust! A carbon fiber-infused inorganic rust-proof primer that excels in workability without the need for release agents or blasting methods.
The product we handle, 'AR-PRIMER 12.5', is an inorganic rust-proof primer for repairing rust on steel materials and protecting newly installed steel frames from rust. It is a polymer cement mortar-based primer that forms a strong coating from emulsions and compounds, effectively blocking water and oxygen, which are the causes of corrosion (rust). It contains carbon fibers to enhance strength, and the coating protects the steel from external exposure. 【Three Key Points of AR-PRIMER 12.5】 ▲ Rust and Corrosion Resistance With a strong alkalinity of approximately pH 12.5, it passivates red rust. ▲ Workability Surface preparation requires at least three types of grinding. ▲ Environmental and Safety Considerations An inorganic, environmentally friendly alkaline product. 【Other Features】 ■ Contains carbon fibers to enhance electrical insulation and surface strength. ■ Forms a stable rust-proof layer that suppresses corrosion and re-corrosion of steel materials. ■ The coating excels in elasticity and adhesion, providing long-term rust prevention. ■ The application in two colors, gray and green, helps prevent missed spots and contributes to construction management. ■ Contributes to reducing repair costs for metal components such as steel structures. ■ Being solvent-free, it allows for environmentally safe construction in river and marine structures. *For more details, click on the 'PDF Download' or 'Contact Us' button!
