Corrosion inhibitor: MBT-Na 40% CAS# 2492-26-4
Product Name: copper corrosion inhibitor Sodium salt of 2-Mercaptobenzothiazole (MBT-Na) CAS# 2492-26-4
Synonyms : MBT-Na;2-MBT;2-Mercaptobenzothiazole;2-Benzothiazolethione
CAS Number:2492-26-4
Molecular Formula: C7H4NNaS2
Molecular Weight: 189.22
Density: 1.12±0.1g/cm3
Appearance: Pale yellow transparent liquid
Application: MBT-Na can be used as the copper corrosion inhibitor in circulating cool water system. The mechanism is due to the chemical absorption of MBT-Na on copper surface, or chelation reaction between them. The dosage of 4mg/L is preferred. This product can also be used as plasticizer and photometer for acid copper plating.
