VpCI Corrosorber paper is a tarnish inhibiting packaging paper specifically for precious metals such as silver, gold and tin. VpCI Corrosorber paper is a unique product in that one side of the paper has a special coating that scavenges or seeks out hydrogen sulfide (H2S) gas. When a significant amount of H2S gas has been absorbed by the paper, the paper will change color from light blue to brown. On the other side of VpCI Corrosorber paper is a tarnish inhibitor that will protect precious metals for up to two years or until the opposite side of the paper has significantly changed color from light blue to brown. VpCI Corrosorber Paper will eliminate the need for coatings and tarnish removers that are often associated with precious metals. Rest assured, knowing that your valuable precious metals will have the same exact appearance as prior to using VpCI Corrosorber Paper. VpCI Corrosorber Paper will in no way hinder further processing of your precious metals. VpCI Corrosorber Paper is simple to use. Simply wrap your precious metals and fold edges together so there is no free airflow. The VpCI coating on the paper vaporizes, reaching all metal surfaces to provide complete tarnish inhibition. With many tarnish inhibitors, there is a need to remove after use, but with VpCI Corrosorber paper, there is no removal needed of the inhibitor. VpCI Corrosorber paper will in no way affect further processing of the precious metal or affect the physical properties such as conductivity or surface resistivity.
VpCI Corrosorber paper can be used to protect products for storage and/or shipment in a wide variety of ways. Use VpCI Corrosorber paper for single item packaging or for multiple item packaging. Common uses include: Electrical components/controls and finished products (silverware, jewelry, etc.)
- Contains hydrogen sulfide scavenger and saturation indicator
- Effective against aggressive environments including humidity, SO2, H2s and galvanic corrosion from dissimilar metals
- Combines protection from tarnish and packaging into one step
- Non-toxic. Contains no nitrites, phosphates, silicones, chromates or other heavy metals.
METHOD OF APPLICATION:
VpCI Corrosorber Paper is a multicolored paper. One side being white and the other side blue. When packaging, the white colored side of the paper must face the metal. The opposite side of the paper, which is blue, will then absorb contaminants, thus preventing them from reaching the surface of the metal. Products should be packaged as soon as possible after cleaning and be completely dry of residual water. Keep VpCI Corrosorber Paper near the surface of the product as practical, leaving no barrier between the paper and the metal surface./p>
Use approximately one square foot of VpCI Corrosorber Paper for every three square feet of surface to be protected, and one square foot Corrosorber Paper for every 0.5 feet of void space. For long term storage exceeding two years, enclose the wrapped product in an airtight package.
