Cortec Produces Multimetal Corrosion Protection Paper

Published: November 13, 2013

ST. PAUL, MN | Utilizing high-tech, patented, recyclable, and repulpable technology, Cortec has produced a multimetal corrosion protection paper, VpCI-144, powered by Nano VpCI, the moisture barrier corrosion inhibiting paper.

VpCI-144 is an environmentally safe replacement for polyethylene (PE) and wax papers, with water vapor barrier properties that are comparable to PE-coated paper. It is suitable for use with food processing equipment components not in direct contact with food, as recommended by FDA. This paper combines corrosion protection, moisture barrier properties, and oil and grease resistivity into one step.

Cortec's VpCI-144 is simple to use and made from the highest quality recycled neutral/natural kraft paper and is coated with a water-based barrier coating. In manufacturing process there is no chlorine or other bleaching chemicals. This is said to completely eliminate package contamination found with other VCI/VPI papers on the market.

Historically, polyethylene and wax coatings have been used to seal porous paper to provide a moisture barrier and/or moisture-vapor barrier. When coated this way, the resulting paper product is an environmental problem and cannot be recycled through normal channels.

Cortec VpCI-144 paper provides superior corrosion protection for both ferrous and non-ferrous metals, which eliminates the need to inventory a variety of papers for all the different types of metal you need to protect.

Cortec VpCI-144 is non-toxic, non-irritating, nitrite and amine free, and fully recyclable/repulpable. It does not contain any silicones, chromates, other heavy metals or toxic products. That means it can be recycled into other types of paper products such as boxes, cardboard, and other corrugated materials. It also can be repulped: made into or mixed with pulp to make new paper products.

Parts protected with Cortec VpCI-144 can be painted, welded, and soldered. The thin protective film doesn’t influence physical properties of most sensitive electrical and electronic components, including conductivity and resistivity. The paper base stock for the VCI/VPI coatings is produced with closely packed cellulose fibers that form a relatively non-permeable sheet. This attribute produces a uniform coating, as well as prevents the coating from striking through the paper. Protective film does not need to be removed prior to further surface finishing or coating application.

Cortec® VpCI-144 paper can be used to protect products for storage and shipment in a wide variety of ways: end closures for shipping tubes, insert strips for recessed areas in large packages, and as sheet liners or separators between products.

Typical applications are: metal producing, metal forging and die casting, metalworking, finished products, electrical and electronic components, controls, etc. VpCI-144 conforms to Military specifications MIL-P-3420E, NACE Standards TM0208-2008 and RP0487-2000, TAPPI Useful Method 253, and is RoHS compliant.
