Sodium Methylbenzotriazole
CAS No.: 15217-42-2
Main Application Fields
1. High-efficiency Metal Corrosion Inhibitor
This product acts as a premium anti-tarnish and anti-corrosion agent for multiple metallic substrates including copper, silver, lead, nickel and zinc. It firmly adsorbs onto metal surfaces to build a compact isolation protective film. This dense barrier effectively isolates metals from oxygen, moisture and corrosive contaminants in the surrounding environment, fully suppressing metal oxidation and corrosion degradation.
It is an ideal protective additive for circulating cooling water loops, heat exchange units, air conditioning machinery and all other facilities equipped with copper alloy parts, delivering long-term stable anti-corrosion protection under continuous circulating operation.
2. Functional Formulation Additive
Beyond water treatment systems, it can be incorporated as a functional auxiliary ingredient into lubricating oils & greases, industrial coating formulas and synthetic detergent systems. It significantly optimizes the overall functional performance of finished products and effectively prolongs their service cycle while maintaining stable long-term efficacy.
