NINGBO INNO PHARMCHEM CO.,LTD. is pleased to offer high-quality Benzotriazole (BTA), a vital chemical compound widely recognized for its exceptional properties, particularly as a potent corrosion inhibitor. Available primarily in powder and granular forms, BTA is a cornerstone ingredient in numerous industrial formulations requiring reliable metal protection.

The versatility of Benzotriazole makes it indispensable in a broad spectrum of applications. A primary use is in water treatment systems, especially closed circulating cooling water systems, where it prevents corrosion of metallic components. Its efficacy is particularly notable for copper and its alloys, but it also provides protection for other metals including silver, lead, cast iron, nickel, and zinc. Beyond water treatment, BTA is a key component in anti-rust oils, automobile antifreeze formulations, and metalworking fluids like grinding and cutting oils. It also finds application as a photographic antifogging agent, a polymer stabilizer, a lubricant additive, and a UV absorber, stabilizing sensitive products.

The anti-corrosive power of Benzotriazole stems from its unique ability to interact directly with metal surfaces. Specifically for copper, BTA forms strong covalent and coordination bonds with copper atoms. This interaction results in the formation of a durable, multi-layer protective film on the metal surface. This film acts as a barrier, preventing oxidation-reduction reactions and inhibiting the corrosion process. The film formation mechanism is highly effective and provides long-lasting protection under various operating conditions. It also has similar protective effects on lead, cast iron, nickel, and zinc.

Benzotriazole can be effectively used in conjunction with various scale inhibitors, bactericidal agents, and algae-killing agents, making it particularly suitable for complex water treatment systems. In automotive antifreeze mixtures containing glycol and water, BTA addition provides vapor phase protection to materials. As a good ultraviolet light absorber, it helps stabilize products sensitive to UV radiation, preventing discoloration in materials like paper, woven fabrics, films, and metal coins.

NINGBO INNO PHARMCHEM CO.,LTD. ensures the supply of Benzotriazole (BTA) meeting stringent quality standards. Our product, typically supplied as a white powder or granules, boasts a high purity level, consistently exceeding 99.5%. Key specifications, such as melting point (within 96.0-99.0°C), low moisture content (Max 0.1%), and minimal ash content (Max 0.05%), are rigorously tested to guarantee consistent performance. The high quality ensures optimal efficacy in all intended applications. The product also passes standard tests for chroma and alcohol solubility, demonstrating its high standard.

Proper storage is crucial for maintaining product quality. Benzotriazole should be stored in a cool, dry, and well-ventilated area, sealed tightly and kept away from sources of ignition and oxidizing agents. Protection from moisture, direct sunlight, and heat is essential during both storage and transportation. Typical packaging includes lined plastic bags, outer wooden barrels, or glass bottles, ensuring product integrity.
