While Cortec’s VpCI®-368 coating protects metal substrates that are exposed to harsh outdoor conditions, with the addition of vapour phase corrosion inhibitors, it has been made more powerful.
The dark brown viscous liquid dries into a firm moisture-displacing wax like film, which can be removed by mineral spirits or alkaline cleaners, such as Cortec VpCI-414. The film can be used for a variety of applications where heavy duty corrosion protection is needed, including: pipe coating, parts storage, underbody coating, wire rope, steel plate and machined parts.
VpCI-368 has an extensive record of being used for the mothballing and laying up of equipment, protection of shipments and preservation of spares. However, now, VpCI-368 extra vapour protection (EVP) is also available for application in complex sealed spaces, where a greater concentration of vapour inhibitor is beneficial. An additional dose of Cortec VpCI vaporises from the coating, fills the enclosed space and adsorbs on difficult-to-reach surfaces. This is helpful on applications such as pipe internals, where it is challenging to thoroughly cover all metal substrates.
VpCI-368 EVP coating offers excellent outdoor protection, which is much easier to handle and remove than traditional wax-based coatings. The coating is UV resistant and passes 900 - 1500 hrs of ASTM B-117 intense salt spray testing applied at 2 - 3 mils on carbon steel. It also provides multi-metal protection on stainless steel, copper, aluminium and cast iron.
