Since the 1950’s, industrial water treatment has primarily used benzotriazole derivatives for yellow metal (copper, copper nickel, and admiralty heat exchangers) corrosion control.
Azole-based technology do have drawbacks and limitations.
The main negative aspects include elevated aquatic toxicity, generation of adsorbable organic halides (AOX) and loss of metal surface passivation when exposed to oxidizers.
More recently, material availability is another limitation that has complicated traditional azole technology use.
Supply chain issues around raw materials, government-imposed tariffs and shipping delays have affected supply and driven costs up significantly, prompting end users to seek out new technologies that reduce their dependency on this technology.
State of the art surface science technology (XPS, ToF-SIMS, TEM) has aided in the understanding of how passivation films are constructed at a molecular level on metal surface.
This has allowed for the development of a novel “engineered copper passivation” (ECP) protective system of components that form an electrically insulating barrier to inhibit corrosion.
The technology works by forming a dynamic “co-film” that integrates low level azoles, patent pending chemistry, and various salt colloids present in cycled water chemistry.
This solution significantly reduces end user’s dependency on azole chemistry, easing the pain brought on by supply chain issues while improving asset protection and environmental compliance.
