Provides economical environmentally friendly temporary corrosion protection to metal substrates.
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.
Features:
- Effective for a broad range of applications to stop 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
- Multimetal protection
- Effective in low dosages
- Does not contain free amines
Typical Applications:
- Inhibitor for closed loop cooling systems
- Fire extinguishing systems
- Inhibitor for hydrostatic testing of pipelines, casings, tanks, and valves
- Inhibitor for packer fluid applications
- Prevents water-bottom corrosion in oil storage tanks
- Alkanolamine sweeteners
- Pulp and paper process equipment
- Mines, mining, and earth moving equipment
- Inhibitor for lay-up application of cooling towers
Dosage:
Closed loop operational systems start at 2,500-3,000 ppm (0.25-0.3 wt.%)
For seasonal wet lay-up application (up to 6 months) use VpCI-649 at a concentration of 0.5 wt.% of inhibitor by volume.
For hydrotest and drain applications contact us for dosage information
For systems already using Molybdate, please use VpCI-649 OF which does not contain tracer.
