Cortec VpCI®-644 Additive

Product Description

VpCI-644 is an additive that protects ferrous and nonferrous metals from corrosion induced by waters containing inorganic salts, including chlorides. As a concentrated formulation, VpCI-644 offers low dosage effectiveness as a treatment for a wide variety of marine and process applications requiring economical corrosion inhibition for fresh water, salt water, and brine solutions. VpCI-644 contains organic ingredients and has strong film persistency abilities. VpCI-644 is effective as a replacement for formulations containing nitrites, phosphates, chromates or other heavy metals.

Features

• Prevents corrosion from fresh and salt water, brine, chloride, and other dissolved halogens of ferrous and non-ferrous metals.
• Nitrite/chromate/zinc/phosphate-free.
• Low concentration effectiveness provides economical treatment.
• Residual protection after hydrotest solution is drained out is 1 to 2 months.
