Cortec’s VpCI-389 is an environmentally friendly water-based, temporary coating that delivers exceptional multi-metal protection for outside and indoor applications. This contemporary coating is an advanced, safe replacement for hazardous oil-based products. It is an excellent choice for long-term indoor protection that lasts up to 5 years and short to medium-term (6-24 months*) unsheltered outdoor protection.

This completely safe and easy to use coating cures to a soft film and eventually hardens. It is very efficient in SO2 and H2S environments. The product leaves a translucent, waxy coating that is easily removable, it is low in VOC’s and dilutable with water. VpCI-389 can be easily removed with alkaline cleaners, such as Cortec VpCI-414. It is available in ready-to-use form – VpCI-389 D (1:1). Metals protected are: aluminum, steels, cast iron, copper alloys and tin plated steel.

Traditional coatings rely on sacrificial metals (zinc, chromates, aluminum) for inhibition. Due to the large particle size of these inhibitors, gaps exist, which allow corrosion to start and eventually expand, causing coating failure. Cortec VpCI-389 coating uses the patented VpCI technology to protect the metal substrate with a tight bonding molecular structure. This system eliminates the gaps which occur with traditional inhibitors and prevents corrosion from starting. With environmentally safe VpCI technology, the equipment and products will get superior corrosion protection.

VpCI-389 coating was tested with excellent results in ASTM D-1748 (humidity chamber test) and ASTM B-117 (salt spray chamber test). It is in compliance with RoHS requirements.
