Corrosion Inhibition Coating

Cortec has added extra vapor phase corrosion inhibitors to its VpCI-368 coating so that it may better protect metal substrates exposed to harsh outdoor conditions. The dark brown viscous liquid dries into a firm moisture-displacing wax-like film that 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 is UV resistant and passes 900 to 1,500 hours of ASTM B-117 intense salt spray testing applied at 2 to 3 ml on carbon steel. It also provides multimetal protection on stainless steel, copper, aluminum, and cast iron. The cured film is heat stable up to 392°F (200°C) and is commercially equivalent to MIL-PRF-16173E (Grades 1 and 2). It can be applied by spray or brush.
