Cortec VpCI®-352

Product Description

VpCI®-352 is a multimetal Vapor phase Corrosion Inhibiting (VpCI®) coating designed for flexible packaging and corrugated board applications. Common applications for coated substrates include interleaving and individual parts wrapping. When metal articles are enclosed within, the VpCI® coating on the substrate vaporizes, reaching all metal surfaces to provide complete corrosion protection.

Method of Application

VpCI®-352 should be applied directly to the paper or board with traditional paper coating applicators such as rod, blade, or spray. Drying can be accomplished by passing the coated substrate through a warm air oven or with IR bulbs.Dry coating weights of 3 – 5 lbs/3000 sq. ft. ream (4.9 – 8.2 gsm) are recommended. In applications where long term protection is required or a highly reactive metal will be packaged, heavier coat weights are suggested.

This product is also available in a super concentrated version, VpCI®-352 SC. This can be applied as is or diluted with water to the desired non-volatile content.

Packaging 

VpCI®-352 and VpCI®-352 SC are available in 5 gallon (19 liter) plastic pails, 55 gallon (208 liter) metal drums, totes, and bulk.
