When working with ferrous metals, flash rusting is always an issue. High humidity in foundries can result in flash rusting which is why foundry corrosion inhibitors are required. As with many applications, aqueous systems have been preferred for both health and safety reasons.
Our water-based rust and corrosion inhibitors provide ferrous corrosion inhibition, exceptionally good wetting and hard water compatibility.
Our flash rust inhibitors have found utility in both spray and dip tank applications with excellent results for both short term and long term storage.
FoundryGeneral Rust Inhibitor 4288 is a concentrated water-based rust and corrosion inhibitor that provides both humidity cabinet and Cast Iron Chip Test (IP287) protection. As a concentrate, FoundryGeneral Rust Inhibitor 4288 can be diluted as required to provide economical protection for ferrous metals. FoundryGeneral Flash Rust Inhibitor 4288 contains surface active agents that are extremely effective at inhibiting the attack of ferrous metals by aqueous solutions.
