| Description: 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 is effective as a replacement for nitrite, bromate, and/or chromate-based formulations. VpCI-649 combines contact and volatile corrosion inhibitors along with anti-scalants in non-toxic formulation that does not contain nitrites, phosphates, chromates, or heavy metals. This product helps solve the problem of disposal, particularly for large quantities of water. VpCI-649 is also available in a cold weather version for the convenience of storage in cold temperatures. | ||
