Corrosion of metal parts is often overlooked during storage and shipment. Anti-corrosion specialist Cortec has solved this problem with CorShield Creped Paper.
An economical packaging solution, the paper combines corrosion protection and packaging into one step and eliminates package contamination. By providing protection for both ferrous and non-ferrous metals it eliminates the need for a variety of papers for all the different types of metals and alloys requiring protection.
CorShield Creped Paper can be used to protect metal products in a variety of ways: single item packaging, interleaving, end closures for shipping tubes, insert strips for recessed areas in large packages, and as sheet liners or separators between products. It is particularly suitable for the bearing industry as it offers cushioning, corrosion protection and a “pooling” effect for RP oils.
The VpCI coating on the paper vaporises, reaching all metal surfaces to provide complete corrosion protection. The inhibiting action of the VpCI forms a very thin protective layer that does not alter the appearance of products or require removal before further finishing or use. This protective layer does not influence the physical properties of most sensitive electrical components, including conductivity and resistance.
Corshield Creped Paper is effective against aggressive environments such as humidity, SO2, H2S, and galvanic corrosion from dissimilar metals. Parts protected can be painted, welded, and soldered. The paper conforms to military specifications MIL-PRF-3420 and is RoHS compliant.
The protective paper is fully recyclable and repulpable. It can be recycled into other types of paper products such as boxes, cardboard, and other corrugated materials, and can also be “repulped” or made into or mixed with pulp to make new paper products. Additionally, the paper is environmentally safe, non-toxic, biodegradable, and doesn’t contain any nitrites, phosphates, or silicates. Made from the highest quality neutral natural kraft paper, the paper is made without the use of chlorine or other chemical bleaching.
Corshield Creped Paper is ideal for use in bearing protection during storage and shipment, metal production, metal forging and die casting of raw and machined forgings and castings, as well as metalworking such as stamping, sheet metal work, springs, bearings, fasteners, tube, pipe, and nails. It can also be used with finished products such as engines, machinery, equipment, tools, hardware, appliances, and motors, as well as electrical and electronic components and control.
