Request Information

Zerust® ActivPak® packets offers a new technology of Vapor Corrosion Inhibitor (VCI) combined with a Volatile Flash Corrosion Inhibitor (FCI™) to protect ferrous and aluminum metals in enclosed spaces. This combination goes to work in minutes to protect against both flash rust and long-term corrosion with its progressive VCI chemistry. Do not place in direct contact with copper, brass, or zinc or use more than recommended. Test before use.

ActivPak® provides corrosion control when there are concerns about manufacturing processes and fluids leaving corrosive residues. The packets reduce flash rust and corrosion incidents, even on contaminated parts and in challenging environments. ActivPak® inhibitors form an invisible shield that provides powerful corrosion protection that does not leave a residue and does not need to be removed prior to welding or painting.
