CorrVerter® MCI® Rust Primer




CorrVerter® is a water-based primer recommended for application to rusty or poorly prepared steel surfaces where further corrosion protection is required and good surface preparation is difficult to achieve. CorrVerter® is formulated to penetrate rust, eliminate rust, penetrate to the bare metal, and stop further rusting.

CorrVerter® contains a novel chemical chelating agent that modifies the surface rust into a hydrophobic passive layer. CorrVerter® combines the above mentioned chelating agent with a high solids waterborne latex with extremely low water vapor permeability. The combination of the active chelating agent with a film-forming latex, thickeners and dispersant offers a unique formulation for a primer with excellent protection against re-rusting.

CorrVerter® does not contain tannic or phosphoric acids, provides long-term corrosion protection for poorly prepared substrates, and can be topcoated with solvent-based and water-based paints with no bleeding. For outdoor applications VpCI®-386 or VpCI®-387 can be utilized. For indoor applications, VpCI®-396 may also be used.

The combination of CorrVerter® and VpCI®-396 provides the best immersion coating for submersion in water, salt water, hydro carbons, and high salinity water.
