Environmentally safe corrosion solution for process applications

A biodegradable corrosion inhibitor for marine and process applications —Cortec’s VpCI-643 provides instant, long-term, multi-metal corrosion protection.

VpCI-643 is a concentrated combination of inherently biodegradable corrosion inhibitors and oxygen scavengers that protect ferrous and nonferrous metals from corrosive solutions containing chlorides. 

This new water treatment additive is designed to provide corrosion protection in fresh water, salt water, brine and other highly corrosive solutions containing dissolved halogens. 

As a concentrated formulation, VpCI-643 offers low dosage effectiveness as a treatment for a wide variety of marine and process applications requiring economical corrosion inhibition for fresh and salt water. 

VpCI-643 is an effective replacement for nitrate and chromate-based formulations and hydrazine-based oxygen scavengers. Adding VpCI-643 to closed circuit cooling and heating systems containing brines or water and hydrostatic testing of pipeline, castings, tanks and valves provides corrosion inhibiting levels of above 95%.  

By scavenging oxygen in a liquid system and forming a barrier layer onto a metal substrate, VpCI-643 provides corrosion protection in aggressive chloride-filled environments.

This becomes particularly important in desalination plants dealing with highly corrosive, concentrated chloride stream as a by-product for removing the chloride from seawater to produce drinking water. 

  • Provides effective corrosion protection against aggressive attack of high chloride solutions
  • Effective in a broad range of applications to stop aggressive corrosion by salt or fresh water, and brines
  • Nitrite and amine-free
  • Low concentration effectiveness provides economical treatment
  • Multi-metal protection
  • Readily water-soluble liquid for easy application

Cortec’s VpCI-643 conforms to ASTM G 1, ASTM G 3 Standard Test Methods, NACE Standard TM-01-64 for Laboratory Corrosion Testing of Metal for the Process Industries, and NACE Standard TM 0169-95 for Laboratory Corrosion Testing of Metals.
