Why Sodium Benzotriazole Is a Smart Choice for Automotive Coolants and Antifreeze

 Modern engines rely on coolants and antifreeze to manage heat and protect metal surfaces. Copper, brass, and solder are still common in radiators, heater cores, and fittings—especially in older vehicles and many industrial engines. These metals are vulnerable to corrosion, which can lead to leaks, clogged passages, and overheating.

Sodium Benzotriazole is a key corrosion inhibitor for copper and copper alloys in coolant formulations. It is highly water-soluble and compatible with glycol-based systems, making it easy to incorporate into antifreeze concentrates and ready-to-use coolants.

Advantages in automotive coolants:

  • Protects copper and brass components from corrosion and pitting.

  • Helps prevent solder bloom and radiator clogging.

  • Compatible with many other coolant additives, including silicates, phosphates, and organic acid technologies.

  • Stable over a wide temperature range.

  • Effective at low treat rates.

For coolant manufacturers, using high-quality Sodium Benzotriazole can improve product performance and help meet long-life coolant requirements. For fleets and maintenance teams, it means longer radiator life, fewer repairs, and better engine reliability.

Shandong Kairui Chemistry Co., Ltd. supplies Sodium Benzotriazole to coolant and antifreeze producers around the world. The company is committed to stable quality, competitive pricing, and dependable service.

what is Acetone Oxime use for?

  Acetone oxime is a ketoxime. It is usually used as oxygen scavenger in power plants, passivator in industrial cleaning and anti-corrosion projects, passivating agent in water treatment chemicals, etc. Chemical deoxidant/deoxidizer/deaerator for feedwater. Oxygen removal effect is the same as hydrazine, and the toxicity is greatly reduced. Protecting / protective agent for thermal equipment shutdown. Because of its good reducibility, its aqueous solution can form a good magnetic oxide film on the surface of steel, effectively delaying the corrosion of thermal equipment out of service. Passivation effect (corrosion protection / inhibitor). Use this product instead of toxic reagent sodium nitrite, hydrazine as passivator for thermal equipment after pickling, small pollution, good film quality. diesel fuel primer, intermediate (organic synthesis).
