VCI-649 water-baset Anti-Corrosive Additive

PRODUCT 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, steam and
glycol closed loop systems.
VpCI-649 is effective as a replacement for nitrite/
bromate/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. Being environmentally safe, this product
helps solve the problem of disposal, particularly for large
quantities of water.

aggressive corrosion in systems containing fresh water,
glycol coolants, etc.
Environmentally friendly and nitrite-free
Low concentration effectiveness provides economical
treatment
Vapor phase action provides protection to areas that
contact inhibitors cannot reach
Contains an acrylic polymer to prevent scale formation
Readily water-soluble liquid for easy application
