What Is The Difference Between A Rust Inhibitor And A Rust Preventative?
Updated: Apr 17, 2019
We define a rust inhibitor as a water-based, clear product that is typically used to keep parts from rusting in between processes. Rust inhibitors offer short-term protection for up to 30 days; however, ambient humidity levels can play a factor in the actual life of protection.
In most cases, no additional cleaning is required before painting or secondary operations. To apply a rust inhibitor the part is either sprayed or dipped.
A Chemtrol® rust preventative is a petroleum oil-based product which will protect for six months to a year. The part is typically run through a dipping operation to apply the preventative. Drying times are part and application dependent. In most cases, Rust Preventatives need to be removed before painting and secondary operations.
