VpCI-649 Liquid: Multimetal Closed Loop Treatment
VpCI®-649 is a unique concentrated liquid formulation that protects ferrous and non-ferrous metals from corrosive solutions. In addition, this product is designed to provide long-term protection in fresh water and glycol closed loop systems.
VpCI®-649 combines contact and volatile corrosion inhibitors along with anti-scalants in a formulation that does not contain nitrites, phosphates or chromates. This product helps solve the problem of disposal, particularly for large quantities of water.
VpCI®-649 contains a molybdate tracer. VpCI®-649 MF is molybdate free, and contains a PTSA tracer for easy detection.
VpCI®-649 is also available in a cold weather version, VpCI®-649 Winterized for the convenience of storage in cold temperatures. VpCI®-649 Winterized provides freezing protection during product storage, it does not provide freezing protection to the diluted VpCI®-649 Winterized water solutions.
