Cortec Corporation’s VpCI-641 and VpCI-641 PTSA corrosion inhibitors for hydrotesting and freshwater cooling systems have earned the USDA Certified Biobased Product label. These products represent Cortec’s commitment to developing technologies that use biodegradable and renewable materials where possible, allowing industries to fight corrosion in an environmentally responsible manner. VpCI-641 offers an economical, ‘greener’ alternative to other hydrotesting products on the market that are not biobased and must be used at a higher dosage.

VpCI-641 is a water-based blend of contact and Vapour phase Corrosion Inhibitors for protection of ferrous and non-ferrous metals (including copper, aluminium, and brass) in industrial waters. VpCI-641 contains 69% USDA certified bio-based content and can be used at fairly low concentration levels for greater economy and lower conductivity. VpCI-641 provides corrosion protection during hydrostatic testing and in some cases can be used in closed loop cooling systems filled with fresh water.

VpCI-641 PTSA includes a PTSA tracer option that makes it easier to monitor proper concentration for ongoing effectiveness in closed loops and reused hydrotest water. When it comes time for wastewater disposal, VpCI-641 makes the process easier as a biodegradable water treatment product that does not contain nitrite or phosphate inhibitors.
