WD-40 Specialist® Corrosion Inhibitor is an anti-rust spray ideal for preventative maintenance and use in extreme environments such as high humidity. It has a long-lasting formula to protect metal parts by blocking rust and corrosion for up to 1 year outdoors or 2 years indoors.

How long will VCI paper protect my parts in a sealed bag? If the paper used to package a part and is properly sealed in a Mylar (or other plastic) bag, the paper will remain active inside the packaging for at least 24 months.

Made from high quality neutral natural kraft paper, these paper products do not contain fluorochemicals, nitrites, phosphates, silicones, chromates, or other heavy metals. Cortec® VCI papers are effective against aggressive environments including humidity, SO2, and H2S.

How Does VCI Paper Work? VCI Paper, or Vapor Corrosion Inhibitor, paper emits molecules that settle on metal surfaces and form an invisible layer that protects from corrosion. It protects by interrupting the electrochemical corrosion process caused by moisture, oxygen and contaminants in the atmosphere.

A volatile corrosion inhibitor (VCI) is a material that protects metals from rust. VCI has rusting protection specialty as well as vacuum specialty. Corrosion inhibitors are chemical compounds that can decrease the corrosion rate of a material, typically a metal or an alloy.

VCI packaging paper gives effective corrosion protection with ease of application. Safepack VCI Papers are specially matured kraft paper with one side impregnated with high-tech multi-metal volatile corrosion inhibitors (VCIs).

Anti-corrosion papers provide maximum, long-term protection. Provides excellent rust protection for ferrous metal. On the U.S. Dept. of Defense Qualified Products List (QPL) f or military specification MIL-PRF-3420 (Packaging Materials, Volatile Corrosion Inhibitor Treated, Opaque).

VCI Paper, or Vapor Corrosion Inhibitor, paper emits molecules that settle on metal surfaces and form an invisible layer that protects from corrosion. It protects by interrupting the electrochemical corrosion process caused by moisture, oxygen and contaminants in the atmosphere.

Safepack makes and supply anti-corrosion VCI paper rolls and sheets on a large scale with continuous basis. SP-VCI corrosion inhibitor Paper is stable at normal storage conditions.
