Closed System Cooling Water Treatment
- Buffered, film-forming inhibitor
- Effective on steel, copper and mixed metallurgy systems
- Compatible with glycol and alcohol antifreeze solutions
CorrShieldTM NT402 is an alkaline, buffered, nitrite-based corrosion inhibitor which is designed for use in the treatment of closed water systems. Corrosion control is achieved by establishing a passive inhibitor film on the metal surfaces. This film contains nitrite and organic corrosion inhibitors.
