Cortec VpCI® Corrverter® Water Based Rust Primer
Product Description
CorrVerter® is a fast drying, water-based one coat system (primer) that converts rusted surfaces to a hydrophobic passive layer and prevents further rusting thru the unique formulation of chelating agents and PVC resins. CorrVerter®r 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.

CorrVerter® 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 and is recommended for use on all ferrous metal surfaces as a rust converter/paint primer. The product can be used in situations where proper cleaning or sandblasting is difficult. For outdoor top coat applications VpCI-386, VpCI-387 or VpCI-396 can be utilized. The combination of CorrVerter® and VpCI-396 provides the best immersion coating for submersion in water, salt water, hydro carbons and high salinity water.
Advantages
• CorrVerter® converts rust quickly and can be applied under varying weather conditions • Provides 1000+ hours of corrosion protection with 3-mil (75 microns) application under salt spray conditions (ASTM B 117), on pre-rusted steel parts • Can be topcoated with water and solvent-based topcoats vs. tannic or phosphoric acid-based coatings, which can only be topcoated with solvent-based topcoats • Provides excellent protection against re-rusting (better than tannic or phosphoric acid-based converters) • Water-based • Very low VOC • Non-flammable, non-combustible • Environmentally friendly, non-toxic • Works in HCl, H2S, SO2, & CO2 vapor environments
Applications
Industrial maintenance • General metal • Marine, marine equipment • Holding tanks, storage tanks • Outdoor storage, aircraft, elevators, vehicles
Application Instructions
Recommended that any loose rust be removed with a wire brush and the rusty steel surface washed with high-pressure water to remove excess salt contamination before applying the product. Brush, roll, or spray CorrVerter® with no surface show-through at 3-5 mils wet film thickness. Brush application is preferred to ensure penetration into the rust. The coating can be applied to dry or damp surfaces. The converter can be used as is or may be diluted up to 10% with water. For badly corroded surfaces, a second coat of CorrVerter® should be applied within 20-30 minutes to ensure maximum protection. Allow to air dry 12-24 hours before applying topcoat or putting the coated components into the environment.
Packaging: 1 gallon, 5 gallon plastic containers.
