Product Description

Product Description

ActivTab™(LS) flash corrosion VCI tablets are quick and easy to install. At first, simply place or sprinkle the tablets in the desired area. Next, tightly seal the enclosure to trap the protective vapors inside.

ActivTab™(LS) Tablets diffuse invisible, odorless, and non-toxic ZERUST® Vapor Corrosion Inhibitor technology (VCI) that settles onto exposed metal surfaces inside the enclosure. Once removed, the VCI will dissipate from the metal surfaces, allowing immediate use or further processing. Furthermore, ActivTab™(LS) VCI Tablets work fast to protect ferrous metals and aluminum against flash corrosion and continue to protect for up to 6 months in a sealed enclosure. Additionally, ActivTab™(LS) protects yellow metals such as copper and brass when used as instructed. However, do not place in direct contact, and test before use.
