Cortec® VpCI-146 is the premium corrosion-inhibiting paper in the industry. Our patented vapor-phase corrosion inhibition (VpCI) technology has revolutionized the way metals are protected in an enclosed package. Cortec VpCI-146 paper provides superior corrosion protection for both ferrous and non-ferrous metals. Cortec VpCI-146 multimetal paper eliminates the need for a variety of papers for all the different types of metals and alloys you need to protect. Cortec VpCI-146 is fully recyclable and processable. That means VpCI-146 can be recycled into other types of paper products, such as boxes, cardboard, and other corrugated materials. Cortec VpCI-146 paper is made from the highest quality neutral natural kraft paper; no chlorine or other chemical bleaching is used in its production. This eliminates package contamination found with other competing VCI/VPI papers. VpCI-146 is easy to use. There are no chemical concentrations to calculate, and no chemical tanks or application systems to maintain. Just wrap your products in the paper, and fold the edges together. Use adhesive tape as needed to hold paper folds in place. The VpCI coating on the paper vaporizes, reaching all metal surfaces to provide complete corrosion protection. The protective layer, VpCI-146, has no effect on the physical properties of most sensitive electrical components, such as conductivity and resistance.
