No Sandblasting Allowed? Try CorrVerter for Rusty Surface Prep (Figure: Cortec Europe)
CorrVerter is a fast-drying, water-based one-component primer for rusty surfaces. It contains a unique formulation of chelating agents combined with a high solids waterborne latex that has extremely low water vapor permeability. The combination of these materials converts surface rust into a hydrophobic passive layer, creating a specialty primer with excellent protection against re-rusting of metal surfaces.
How to Apply CorrVerter
CorrVerter can be used almost anywhere a tight layer of surface rust is present. Rather than requiring special equipment or labor-intensive abrasion to remove the corrosion, users of CorrVerter simply need to brush off loose rust before priming right over the surface. Once the surface is primed and passivated, it can be top-coated with either a water-based or solvent-based paint (urethanes, epoxies, acrylics, and alkyds) for further protection and aesthetics. CorrVerter should be applied at 5.8-8.7 mils (147-221 µm) WFT (wet film thickness) in order to achieve a DFT (dry film thickness) of 3.0-5.0 mils (75-125 µm). It shows excellent 5B adhesion.
Simple Surface Prep – Plus
In addition to simplifying surface prep, CorrVerter has several advantages in and of itself. (1) As a water-based coating, CorrVerter is considered to be a more environmentally responsible option and is also easier for workers to clean up. (2) It has an extremely low VOC of 0.1 lbs/gallon (12 g/L). (3) As a single-component system, it is much faster and more convenient to use than primers that require the mixing of two parts together.
Make Life Easier for Yourself and Others
For anyone who encounters rusty surfaces on a regular basis, CorrVerter Rust Converter Primer is an excellent coating to have on hand for easy passivation and surface prep of corroded metals. Maintenance teams, painters, and concrete contractors will find that CorrVerter opens up the exciting prospect of making life easier in the face of corrosion.
