Corrosion Inhibitors & Oxygen Scavengers
TL;DR Corrosion inhibitors are materials used to protect metal surfaces from corrosion.
Corrosion Inhibitors & Oxygen Scavengers are chemicals that protect metal from corrosion and remove dissolved oxygen from cooling, boiler and condensate systems.
In this category: This category covers copper/yellow-metal corrosion inhibitors (benzotriazole BTA, tolyltriazole TTA, mercaptobenzothiazole MBT and their salts), neutralizing amines for condensate (morpholine, cyclohexylamine, MOPA) and oxygen scavengers (DEHA, carbohydrazide). Together they control the galvanic, oxygen-pitting and carbonic-acid corrosion that attack water systems.

Corrosion inhibitors are materials used to protect metal surfaces from corrosion. They work by creating a passive film on the surface of the metal and preventing reactions with oxidizing agents such as oxygen and water vapour. Different types of corrosion inhibitors can be used for different metals, depending on their chemical compositions. In addition, some corrosion inhibitors are designed for specific applications, such as lubricants and coatings. Corrosion inhibitors can be highly effective in protecting metal surfaces from deterioration due to their effectiveness in preventing oxidation, but careful selection is needed for optimal performance and cost-effectiveness.

Choose a corrosion-inhibitor route from the signal and metallurgy
A copper result is not a product-selection shortcut. Confirm the sample, locate the source, distinguish open from closed circulation and map every important wetted metal. Then screen a complete program that protects copper alloys without ignoring steel, aluminum, deposits, microbiology, oxidant exposure or equipment conditions.
| System evidence | Corrosion evidence | Document request |
|---|---|---|
| Open/closed boundary, water analysis, pH, temperature, makeup and treatment history | Dissolved/total copper and iron, alloy map, coupons, deposits and inspection | Exact grade identity, current TDS/SDS, specification, COA format and compatibility evidence |
Start with the copper-signal response guide and the broader Cooling Water Treatment application. Review TTA, BTA and the closed-system inhibitor as candidate identity pages only, then request evidence for the actual water and metallurgy.
