Cortec VpCI®-649 N

Product Description

VpCI-649 N 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 N is effective as a replacement for nitrite, bromate, and/or chromate-based formulations.

VpCI-649 N 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.
