Used as a corrosion inhibitor in industrial water treatment systems, POPULIN is effective in protecting metal surfaces, especially in cooling and heating systems. It functions by forming a protective film on metal substrates, preventing oxidation and degradation caused by water and dissolved oxygen. Commonly applied in oil refineries, power plants, and HVAC systems, it helps extend equipment life and maintain operational efficiency. Its compatibility with various water chemistries and low toxicity make it suitable for both open and closed-loop systems. Additionally, POPULIN is utilized in certain formulations for metal cleaning and surface treatment processes where corrosion control is critical during intermediate manufacturing steps.
