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.
