Used in organic synthesis.

Stannous isooctanoate is a white or light yellowish brown paste, sometimes called stannous octanoate. It is soluble in petroleum ether and insoluble in water. It is a basic catalyst for the production of polyurethane foam, mainly used in the gelation reaction in the foaming of polyether-polyurethane, and can also be used as a polyurethane foam antioxidant. Used as catalyst for polyurethane synthesis and room temperature vulcanization of silicone rubber. Also used as catalyst type curing agent for epoxy resin. Stannous octanoate has greater catalytic activity than dibutyltin dilaurate in curing, and if the two are used in combination, the effect is better than that of using them individually, and it can take into account the speed of reaction and curing. Since dibutyltin compounds are easily oxidized and decomposed by oxygen and water vapor in the air, they should be used for nitrogen protection when stored, and must be sealed, avoiding high temperature and excessive humidity, in order to prevent the activity from decreasing or failing.

Storage and transportation:

Should be sealed and stored in a dry, cool and ventilated warehouse


200KG/drum Storage: it is recommended to store in dry and cool area with proper ventilation. Please fasten the package cover as soon as possible after the original packaging to prevent the mixing of other substances such as moisture and other substances that may affect the product performance. Store in a cool and dry place, keep the container sealed and avoid contact with oxides. Do not inhale dust and avoid contact with skin and mucous membranes. Smoking, eating and drinking are prohibited in the workplace. After work, shower and change clothes. Store contaminated clothing separately and wash before use. Maintain good hygiene practices.
