CASE HISTORY SPOTLIGHT #657: Rust Preventative for Electrostatic Oiler

February 22, 2024

A coil processor wanted to start using an electrostatic oiler after acid pickling in order to reduce the amount of oil used and cut costs. The challenge was to find a rust preventative that was compatible with the electrostatic charge, since many products cannot be applied in this way. The processor worked with the electrostatic oiler manufacturer to test several Cortec^®products, found that VpCI^®-325 was compatible, and began applying it to steel coils. The product had already shown good corrosion protection performance several years before when tested against a common coil industry rust preventative and has been regularly used in the steel processing industry for many years since. It is partially vegetable-oil based, displaces water, and is an excellent solution for processors that need to apply long-term (e.g., two-year) protection using an electrostatic oiler.
