VpCI Corrosorber paper is a tarnish inhibiting packaging paper specifically for precious metals such as silver, gold and tin. One side of the paper has a special coating that scavenges or seeks out hydrogen sulfide gas. When a significant amount of gas has been absorbed by the paper, the paper will change color from light blue to brown. On the other side of the 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. This paper will eliminate the need for coatings and tarnish removers and is very easy 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. There is no removal needed of the inhibitor.

Metals Protected: Silver, Gold, Tin, Iron Alloys, Copper, Brass, and Aluminum Alloys.
Method of Application: VpCI Corrosorber Paper is a multicolored paper with one side being white and the other side blue. When packaging, the white colored face of the paper must face to 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 after cleaning as possible, but completely dried of residual water. For long term storage exceeding two years, enclose the wrapped product in an airtight package.
Non-toxic, contains no nitrites, phosphates, silicones, chromates or other heavy metals. Does contain hydrogen sulfide scavenger and saturation indicator and is effective against aggressive environments, including humidity.
