AQ Shield ≪Super Strong Anti-Rust Primer≫ Rust Preventive Agent Super Strong Anti-Rust Primer AQ Shield Super Strong Anti-Rust Primer is the highest performing anti-rust primer among existing products. The performance comparison of anti-rust primers depends on the epoxy used, and the Super Strong Anti-Rust Primer utilizes high-purity epoxy. Additionally, it uses environmentally friendly epoxy, making it safe to use even in locations where normal environments are hindered. While standard anti-rust primers have a film thickness of around 40μ, the Super Strong Anti-Rust Primer can form a film thickness of 60μ to 80μ, making it effective even on heavily rusted areas. Moreover, the elasticity added to the coating is a unique technology of the Super Strong Anti-Rust Primer, allowing it to robustly defend against the increase of rust. Standard construction anti-rust primers cannot be used on the hull of ships, but the Super Strong Anti-Rust Primer, being high-performance and environmentally friendly, can be used for rust prevention on ship hulls.
