Product Description

Product Description

Use ActivDri™ PWA dual-acting moisture and corrosion control packets to protect highly sensitive metal parts and electrical components from corrosion damage during operation, shipping, and storage.

ActivDri™ PWA Packets diffuse invisible, odorless, and non-toxic ZERUST® Vapor Corrosion Inhibitors (VCI) that settle onto exposed metal surfaces inside the packaging or enclosure. Once removed from the packaging, the VCI will dissipate from the metal surfaces, allowing immediate painting, welding, or further processing. ActivDri™ PWA Packets ferrous metals and aluminum surfaces for up to 12 months in a sealed enclosure and is compatible with yellow metals and silver. Additionally, ActivDri™ PWA Packets comply with Global Automotive Declarable Substance, TSCA, REACH, RoHS, and TRGS615 requirements.
