For any paint and coatings system, it is critical to start out with the right base: good surface prep and priming. But when it comes to Cortec® MicroCorrosion Inhibiting Coatings™, the significance of priming goes beyond the need to smooth out substrate imperfections and promote good adhesion. For those who choose Cortec VpCI®-396, it also means fighting corrosion with a convenient and popular one-component, direct-to-metal (DTM) anticorrosion primer/topcoat that can be used in countless applications.

VpCI-396 is a solvent-based, moisture-cure urethane one-coat system that can be applied DTM in harsh, outdoor, unsheltered applications. Its proprietary blend of VpCI micro-corrosion inhibitors offers protection that competes with many traditional paints and zinc-rich primers. For best results, it should be top-coated with VpCI-384 to form one of Cortec’s toughest anticorrosion coatings systems. However, it can also be used as a standalone primer and/or topcoat if circumstances require. VpCI-396 offers good chemical and corrosion resistance and excellent adhesion to substrates. As a one-component primer, it simplifies application (mixing of two components is not required). VpCI-396 also reportedly reduces coatings waste because there is no pot life to worry about, and remaining paint can be used later.

There are many applications where a good anticorrosion primer/topcoat is needed to protect metal substrates. Tanks are excellent candidates for VpCI-396. For example, ballast tanks that are filled, emptied and refilled with seawater are naturally at higher risk for corrosion. Storage tanks or holding tanks containing anything from hydrocarbons to high-salinity solutions also need protection. Likewise, railings, walkways and other structural steel in chemical manufacturing, wastewater treatment, offshore and other corrosive environments can also benefit from being coated with VpCI-396. VpCI-396 may even be applied as a protective coating on metal roofs.
