Description

VpCI-329 is a vapor corrosion-inhibiting oil-based concentrate for use with lubricating, hydraulic, and preservation oils. VpCI-329 provides excellent protection in sheltered outdoor/indoor conditions. VpCI-329 protects in two unique ways by offering a tenacious film, which clings to metal surfaces as well as vapor phase inhibitors into the air above the oil. The vapors condense and form a protective barrier on metal surfaces that are not in contact with the oil. This combination allows complete protection for internal system parts.
