This self priming, high build coating is designed for minimally prepared sound rusted or clean steel in mild to moderate industrial environments. Two coats are required. It can also be used on concrete, and the excellent elongation properties of 200% make it suitable for bridging small cracks. Noxyde is not recommended for exposure to most hydrocarbon solvents. Noxyde is suitable for over-coating previous coating systems that are in good sound condition. Noxyde is a trademark of the Rust-Oleum Corporation.
