The following is a comprehensive introduction to Sodium benzotriazole/BTAS  CAS 15217-42-2:


Basic Information

Chemical characteristics

Molecular formula: C6H4Na, molecular weight: 141.1134

Appearance: Light yellow viscous transparent liquid (40% -50% concentration) 37 or solid powder (99% purity) 1

Solubility: miscible with water, lower alcohols, ethylene glycol, and also soluble in organic solvents such as chloroform and benzene

CAS number: 15217-42-2

Density: 1.13-1.19 g/ml (liquid, 24 ℃) 

PH value: 10% aqueous solution is 11.2-11.7 (alkaline) 


Core functions

Metal protection: adsorbs onto the surface of copper, brass, bronze and other metals to form a protective film, inhibiting atmospheric and medium corrosion.

Ionic barrier: prevents copper ion migration from causing electrochemical corrosion of metals such as aluminum and iron34.
Environmental compatibility: Non toxic, non corrosive, known as green corrosion inhibitor46.

Application Fields

Industrial media additives

Corrosion inhibiting components of coolant, antifreeze, and metalworking fluid 13
Copper ion stabilizer for synthetic detergents and heat transfer systems 48

Surface treatment
Water based anti rust coatings and oil additives to prevent metal discoloration and deterioration 68

Precautions for use

Compatibility limitation: The alkaline system has good compatibility (pH ≥ 12), but poor compatibility with acidic corrosion inhibitors.

Storage requirements: Seal and store in the dark to avoid failure.
