Product Description

Product Description

ZERUST® ActivPowder™ (LS)-10F is a Vapor Corrosion Inhibitor (VCI) powder designed to protect metal surfaces in large voids from corrosion. It offers VCI protection, combined with a new self-fogging Flash Corrosion Inhibitor (FCI™) technology, specialized in protecting metals in enclosed spaces. This combination is self-fogging and goes to work in minutes to protect against flash rust and provide long-term corrosion protection.

The exceptionally fast diffusion rate of ActivPowder™(LS)-10F inhibitors enables rapid delivery of protection to metal surfaces, even in hard-to-reach spaces of structural voids, tubing, and cavities. It also provides effective surface passivation to protect contaminated metal surfaces from corrosion. In addition, the VCI powder is fully water-soluble and is effective in wet lay-up applications.



ZERUST®/EXCOR® ActivPowder™(LS)-10F VCI Powder is stocked in cases. However, a 5-7 day lead time may apply. Call to confirm. Additional quantities, such as super sacks, are available upon request.
