Cortec CorrVerter® Rust Converter Primer

CorrVerter® Rust Converter Primer can combat rusted surfaces effectively. It is a cutting-edge, fast-drying, and water-based one-coat system.

With these features, it offers unparalleled performance and surpasses conventional primers. CorrVerter® converts rusted surfaces into a hydrophobic passive layer and ensures protection against corrosion.

CorrVerter® combines powerful chelating agents and PVDC resins. These components penetrate deep into the rusted metal and form a stable, protective barrier. This barrier halts the corrosion process.

Preparation and Application for Rust Converter Primer

• Preparing the Surface. Remove grease, dirt, drawing compounds, fingerprints, oil, fingerprints, loose rust, rust inhibitors (except those approved by Cortec®), or other surface contaminations. You can use a wire brush or sandpaper to clean the surface.
• Application. Recommended dew point is at least 5 °F (2 °C) but still lower than the air temperature. Use power agitation to maintain a homogenous consistency with a cylindrical cage type or a handheld drill mixer. For thinning requirements, dilute CorrVerter with water up to 15%. You can spray, brush, roll, or dip metal into the primer, depending on your preference. If you need to apply topcoat on your metal surface, use only Cortec products with high-performance coatings. In case, you want to use other brands and products, make sure to check compatibility for optimum results. Some topcoat brands may render your converter primer useless.
• Cleanup. Proper cleanup of tools and equipment after using CorrVerter® Rust Converter Primer is essential. This preventive task will maintain their longevity and ensure successful future applications. When the paint is still wet, clean tools and equipment immediately with water. This step helps prevent the primer from hardening and becoming challenging to remove. In case the primer has dried on the tools or equipment, you can use butyl cellosolve or methyl ethyl ketone (MEK) for cleaning purposes. However, follow the manufacturer's safety recommendations and guidelines when using any solvent for cleaning. Always use solvent in well-ventilated areas.
• Setting Up the Equipment. You can apply CorrVerter® Rust Converter Primer using various equipment setups.

HVLP and/or Conventional Spray

When using HVLP (High Volume Low Pressure) or Conventional Spray systems, consider the following details:

• Nozzle Tip: Use a nozzle tip size ranging from 0.02" to 0.11" (0.5-2.8 mm) depending on the specific pressures and viscosity of the product. The appropriate nozzle tip selection ensures an optimal application rate and coverage.
• Air Pressure: Maintain an air pressure range of up to 55 psi. This pressure setting helps achieve the desired atomization and ensures a smooth application process.
• Fluid Pressure: Set the fluid pressure at 10 psi to ensure a consistent flow of the CorrVerter® Rust Converter Primer during the application.
• Fluid Hose: Use a fluid hose with an inner diameter (I.D.) of ⅜" (0.95 cm) and a maximum 50 feet (15.2 m) in length. You can also use 0.64 cm I.D. fluid hose, but you’ll have to adjust the pressure. It is important to use a hose of sufficient diameter and length to avoid pressure drop and ensure a steady supply of the product. The pot containing the primer should have dual control. Keep the spray gun elevated but not higher than the pot of primer to maintain consistent application performance. 

Air-Assisted Airless or Airless

For more demanding applications, you can use air-assisted or airless setups to apply CorrVerter® Rust Converter Primer. The following details are essential for this equipment arrangement:

• Nozzle Tip Size: Choose a nozzle tip size ranging from 0.38-0.89 mm or 0.015 to 0.035 in inches depending on the pressures and fluidity. This selection ensures effective atomisation and coating consistency.
• Pressure: Set the pressure to a minimum of 1800 up to 2500 psi to achieve the proper spray pattern and coverage for the Rust Converter Primer.
• Hose: Use a minimum 0.95 cm or an equivalent ⅜" I.D. hose, and if needed, you can attach 0.64 cm or an equivalent ¼" I.D. whipping section to facilitate easier application. A suggested maximum 100 feet for the hose length allows for efficient and flexible coverage.

The appropriate equipment setup will largely depend on the specific project requirements, the surface to be coated, and the application conditions. Always follow the manufacturer's recommendations and guidelines for the best results.
