ZERUST® ActivPowder™(LS)-10F

ZERUST®/EXCOR® ActivPowder™(LS)-10F is a Vapor Corrosion Inhibitor (VCI) powder designed to protect ferrous metal surfaces in large voids from corrosion. This self-fogging powder combines VCI protection with a Flash Corrosion Inhibitor (FCI™) to protect against flash rust and provide long-term corrosion protection.



  • Fast acting and effective on hard-to-reach surfaces
  • Safe* and easy to use
  • Vapor Corrosion Inhibitor Powder protects against flash corrosion
  • Does not cause hydrogen embrittlement
  • Protects against acid gases, salt air, and other challenging contaminants
  • Powerful and long-lasting protection
Product Description

Product Description

The fast diffusion rate of Activ™ inhibitors enables quick delivery of protection, even in hard-to-reach spaces of internal cavities, such as baffles, where sweating and condensation of trapped humidity typically cause corrosion issues. ActivPowder™(LS)-10F also provides effective surface passivation to protect contaminated metal surfaces from corrosion. In addition, the vapor corrosion inhibitor powder is fully water soluble and effectively prevents corrosion after hydrostatic testing.

ActivPowder™(LS)-10F vapor corrosion inhibitor powder is a low-odor, nitrite-free formula and conforms to Vapor Inhibitor Ability (VIA) when tested according to NACE Standard TM0208. ActivPowder™(LS)-10F is non-flammable and complies with Global Automotive Declarable Substance, TSCA, ECHA SVHC, RoHS, and REACH requirements.
