This product is mainly used as antirust agent and corrosion inhibitor for metals (silver, lead, nickel, zinc, copper and copper metals). It is widely used in antirust oil (ester) products, and is mainly used in copper and copper alloy vapor phase corrosion inhibitor, circulating water treatment agent, lubricating oil additive, etc. The product can also be used with a variety of scale inhibitors, bactericides and algicides, especially for circulating cooling water system. It can be used not only in combination with organic corrosion inhibitor, but also in a separate way. Methyl benzotriazole and BTA have the same inhibition effect on copper and copper alloy, but in pickling solution, the inhibition effect of methyl benzotriazole is slightly stronger than that of BTA. When the mixture of methyl benzotriazole and BTA is used, the corrosion inhibition effect is better.
