Product Description

Product Description

ActivCapsule flash-corrosion prevention diffusers are quick and easy to install. First, simply peel back the protective paper from the adhesive tape and install the capsule securely in the desired location. Next, tightly seal the enclosure or packaging to trap the protective vapors inside.

ActivCapsule FAC1-1(S) diffuses invisible, odorless, and non-toxic ZERUST® VCI molecules that settle onto exposed metal surfaces inside the packaging or enclosure. Once removed from the packaging or enclosure, the VCI will dissipate from the metal surfaces, allowing immediate painting, welding, or further processing. Moreover, ActivCapsule FAC1-1(s) works fast to provide flash-corrosion prevention for aluminum and protects ferrous metals for up to 1 year in a sealed enclosure. Additionally, ActivCapsule FAC1-1(s) protects yellow metals such as copper and brass when used as instructed.
