Zerust ActivPak (LS) packets offer a new technology of Vapor Corrosion Inhibitor (VCI) combined with Volatile Flash Corrosion Inhibitor (FCI) to protect ferrous, non-ferrous, and aluminum metals in enclosed spaces. This combination goes to work in minutes to protect against both flash rust and also against long-term corrosion with its progressive VCI chemistry.

Use ActivPak to protect electronics, equipment and assets in corrosive environments such as in salty air, sewage treatment plants or power plants. The packets reduce flash-rust and corrosion incidents even on contaminated parts and in challenging environments. ActivPak provides corrosion control when manufacturing processes are not in full control and there are concerns with process fluids leaving corrosive residues.
