Copper corrosion inhibitor benzotriazole BTA can adsorb on the metal surface to form a thin film, protecting copper and other metals from atmospheric and harmful media corrosion; Copper corrosion inhibitor BTA can be used in conjunction with various scale inhibitors, bactericides, and algae killing agents in circulating cooling water systems. It has a good corrosion inhibition effect on circulating cooling water systems, with a dosage of 2-4mg/L in circulating water. BTA can also be used as an anti discoloring agent for copper and silver, as well as an additive for automotive coolant and lubricating oil.

Copper corrosion inhibitor methylbenzotriazole TTA can be used as a corrosion inhibitor for non-ferrous copper and copper alloys, as well as for ferrous metals. The copper corrosion inhibitor TTA adsorbs on the metal surface to form a thin film, protecting copper and other metals from the corrosion of harmful media in the atmosphere and water. The copper corrosion inhibitor TTA forms a more uniform film and has a better effect when combined with mercaptobenzothiazole (MBT).

Copper corrosion inhibitor mercaptobenzothiazole MBT can be used as a copper corrosion inhibitor in circulating cooling water systems. The corrosion inhibition effect of copper corrosion inhibitor MBT mainly relies on chemical adsorption with active copper atoms or copper ions on the surface of metallic copper; Alternatively, chelation may occur to form a dense and strong protective film, providing good protection for copper equipment. The usage amount is generally 4mg/L. MBT can also be used as a plasticizer, acidic copper plating agent, etc.

Imidazoline series hydrochloric acid pickling corrosion inhibitors belong to the imidazoline class of products. When cleaning metals with acid, adding acid pickling corrosion inhibitors can suppress the corrosion of acid on steel. The prerequisite for the application of acid pickling corrosion inhibitors is that the cleaning medium is hydrochloric acid, sulfuric acid, and amino sulfonic acid, and the cleaning object's substrate is black metal. Acid pickling corrosion inhibitors are suitable for the pickling of various models of high, medium, and low pressure boilers, as well as for the pickling of large equipment and pipelines. Corrosion performance in acid solution (dosage of 1-3 ‰).
