Priming Rusty Surfaces for Success with CorrVerter®

June 8, 2021

 A good primer is an important foundation to achieving a successful coatings system that has a smooth profile and good adhesion to metal. This is even more critical when the surface being coated is rusty. In many cases, the rust has to be sand blasted off in order to ensure a clean surface for the primer to adhere to, but with CorrVerter® Rust Converter Primer, the story takes an interesting turn.

CorrVerter® is a fast drying, water-based one-coat system (primer) that converts rusted surfaces to a
hydrophobic passive layer and prevents further rusting through the unique formulation of chelating agents and PVDC resins. This is an ideal solution for situations where blasting is not an option due to site
restrictions or other limitations.

CorrVerter® offers outstanding corrosion protection in salt spray testing conditions and provides excellent 5B adhesion to topcoats. It has the flexibility of being used with either water-based or solvent-based topcoat systems including urethanes, epoxies, acrylics, and alkyds. Further to the benefit of workers, CorrVerter® has low VOC (0.1 lbs/gal [12 g/L]) and is easy to clean up.

If you are looking for a great way to prime a rusty surface and prepare it for coating without extra sandblasting and hassle, CorrVerter® is an excellent alternative to get off to a good start for coatings success. Contact Cortec® to learn more and get ready to give it a try!
