Primer for Corrosion Protection

Cortec Corrosion Solutions India Pvt Ltd offers VpCI CorrVerter, a water-based Primer for Corrosion Protection. This is recommended for application to rusty or poorly prepared steel surfaces where further corrosion protection is required and good surface preparation is difficult to achieve. VpCI CorrVerter is formulated to penetrate rust, eliminate rust, penetrate to the bare metal, and stop further rusting. VpCI CorrVerter contains a novel chemical chelating agent that modifies the surface rust into a hydrophobic passive layer. VpCI CorrVerter combines the above mentioned chelating agent with a high solids waterborne latex with extremely low water vapour 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. VpCI CorrVerter does not contain tannic or phosphoric acids, provides long-term corrosion protection for poorly prepared substrates, and can be top coated 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 VpCI Corrverter and VpCI-396 or VpCI-395 provide the best immersion coating for submersion in water, salt water, hydro carbons and high salinity water. Therefore this coatings combination is Cortec’s best offer for immersion situations. Typical applications: VpCI CorrVerter 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: industrial maintenance, general metal, marine, holding tanks, etc.
