Weldable Corrosion Inhibitor
According to testing by a heavy equipment manufacturer, Daubert Cromwell’s ready-to-use Nox-Rust 5400 rust-prevention coating doesn’t compromise weld quality or contribute to hydrogen-induced cracking.

Nox-Rust 5400 from Daubert Cromwell (Alsip, IL) is known as an effective corrosion inhibitor, providing protection for cold-rolled steel and metal stampings as well as metal parts used in the automotive, heavy equipment and machinery industries. The light oil leaves a lubricating film that doesn’t interfere with stamping oils or processing oils.
Recent testing by a heavy equipment manufacturer shows the volatile corrosion inhibitor (VCI) oil is also an effective weldable rust preventative (RP). Plates were welded together without having to remove the protective coating with solvents or cleaning solution. The welding process and the weld itself were unaffected. During side-by-side comparative testing, Nox-Rust 5400 produced minimal splatter and didn’t require as frequent cleaning of the weld nozzle, both important cost-saving considerations.
Corrosion protection on welded metals lasts for up to 5 years (indoors).
Nox-Rust 5400 is available in an 11-ounce aerosol spray, 5-gallon pails, and 55-gallon drums.
