PRODUCT NAME: Sodium salt of 2-Mercaptobenzothiazole (MBT•Na)
CAS NO.: 2492-26-4
MOLECULAR FORMULA: C7H4NNaS2
MOLECULAR WEIGHT: 189.22
MOLECULAR STRUCTURE:
Na-MBT is a 2-mercaptobenzothiazole sodium salt, which belongs to water-soluble thiazole type vulcanization accelerator. The raw material is prepared by refining and blending MBT sodium salt. It is mostly a light yellow to brown transparent liquid. It is suitable for water-based latex, recycled rubber and various synthetic rubbers. It has good water solubility, uniform dispersion, mild vulcanization reaction, and is less likely to cause local scorching. It is often used as a vulcanization aid for latex products, sealing parts, and waterproof rubber accessories, which can make the rubber cross-linking more stable and the finished product has better elasticity and toughness.

Properties
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.

FAQ
Q: How to choose between Na-MBT and solid MBT?
A: For water-based systems, Na-MBT is preferred; for dry rubber compounding, solid MBT is more suitable.
Q: What are the storage requirements?
A: Store at room temperature in a dark place, avoid high-temperature exposure, and prevent concentration stratification.
Q: Which additives can be combined with it?
A: It can be combined with zinc oxide, stearic acid, and sulfonamide-type accelerators to improve the vulcanization efficiency.
