Molecular formula: C 16 H 30 O 4 Sn
Molecular weight: 405.11
CAS number: 301- 10-0
Product Features and Advantages
Highly active catalysts and antioxidants used in the production of polyurethane and room temperature curing silicone rubber products. It has high catalytic efficiency and controllable stability, which is more environmentally friendly and safer. The product is insoluble in water and soluble in water. In petroleum ether, polyol.
Product Usage
Commonly used as a catalyst for polyurethane products and room temperature curing silicone rubber. Because it is a divalent tin compound, it is easily oxidized to a tetravalent tin compound after foaming. It can act as an antioxidant when left in the foam and has no adverse effect on the foam. Also used as epoxy resin catalyst curing agent. During curing, stannous octoate has greater catalytic activity than dibutyltin dilaurate. If they are used in combination, the effect will be better than when used alone.

Storage Precautions
Since divalent tin compounds are easily oxidized and decomposed by oxygen and water vapor in the air, they must be protected with nitrogen during storage and must be sealed to avoid high temperatures and excessive humidity to prevent activity decline or failure. Store in a cool and ventilated warehouse and should be stored separately from oxidants.
