VpCI-386 from Cortec Corporation (St. Paul, MN) is a fast drying, water-based acrylic one coat system that can be applied DTM (direct to metal) for corrosion protection in outdoor unsheltered applications. It offers a variety of environmental and user benefits, and is good alternative to solvent-based corrosion inhibitor coatings and has a low VOC of 0.6 lbs/gal (72 g/L).
As a water-based product, VpCI-386 is able to compete with many paints and zinc-rich coatings thanks to the power of Cortec’s “NANO” VpCI inhibitors. These inhibitors fight micro-corrosion by forming a molecular protective layer that follows the intricacies of the substrate’s micro-cavities. This offers fuller inhibitor coverage than traditional sacrificial metal inhibitors, which leave gaps due to their relatively large particle sizes. Implementing VpCI-386 allows users to lower environmental impact by reducing VOCs while also minimizing worker exposure to solvents and making coating cleanup easier.
