VpCI-649 Powder


Vapor phase technology based cloosed loop treatment system that is nitrate, borate, chromate-free and environmentally safe.


VpCI-649 Powder is a unique powder formulation for protecting different metals against corrosion. It is designed to provide long-term protection in open and closed loop cooling systems.

VpCI-649 Powder combines contact and volatile corrosion inhibitors in a non-toxic, biodegradable formulation that does not contain nitrites, phosphates, chromates, or heavy metals. Being environmentally safe, it helps solve the problem of disposal, particularly for large quantities of water. VpCI-649 Powder also contains a blend of organicbased scale inhibitors, which prevent scale formation in pipes and towers.

• Biodegradable, environmentally friendly, and nitrite-free
• Low concentration effectiveness provides economical treatment
• Vapor phase action provides protection to areas that contact inhibitors cannot reach
• Readily water-soluble
• Multimetal protection of copper, steel, zinc, aluminum, etc.
• Easy application
• Does not contain free amines
• Economical (100% active)
• Easily traceable utilizing a Molybdenum test kit.

VpCI-649 Powder contains 1.2% Mo by weight, in the form Na2MoO4• 2H2O (at 3.0% of total formulation). See reversed side for Mo vs. VpCI-649 Powder concentration chart



• Unique inhibitor/antiscalant for open and closed loop cooling systems
• Fire extinguishing systems
• Inhibitor for hydrostatic testing of pipelines, casings, tanks, and valves
• Excellent for lay-up of cooling towers



VpCI-649 Powder should be added starting at (1500- 2000 ppm) by weight to the water.
