Product Description
What Is Stannoue Octoate T9?
Stannous Octoate T9 is a tin(II) salt of octanoic acid (also known as octoate), commonly used as a catalyst in the production of polyurethanes, plastics, and coatings. It is crucial for sectors including chemical manufacture, construction, and the automobile industry since it speeds up the curing and polymerization processes. It is particularly valued for its role in enhancing the efficiency of reactions in polyurethane foam production and silicone rubber curing.
Preparation Method:
Stannous Octoate T9 is synthesized by reacting stannous chloride (SnCl2) or stannous oxide (SnO) with octanoic acid in the presence of an organic solvent like toluene or xylene. In order to encourage the creation of stannous octoate, the mixture is heated to 150°C to 180°C. Afterward, the product is purified through distillation or vacuum evaporation to remove excess solvents and unreacted materials. The final product is a pale yellow to brown liquid, soluble in organic solvents and commonly used in various industrial applications requiring rapid curing.
