When it comes to finding a water-based coating for outdoor corrosion protection, VpCI®-386 is a great place to start. VpCI®-386 is a fast drying, water-based acrylic one coat system (topcoat) that can be applied DTM (direct to metal) for corrosion protection in outdoor unsheltered applications. It offers a variety of environmental and user benefits.
VpCI®-386 is a good alternative to solvent-based corrosion inhibitor coatings. VpCI®-386 has a relatively low VOC of 0.6 lbs/gal (72 g/L), well below the typical cutoff of 3.5 lbs/gal (419 g/L) for VOC compliance in many regions. 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.
