Uses.
Used in organic synthesis.
Stannous isooctanoate is a white or 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 of polyether-polyurethane foaming, and also as an antioxidant for polyurethane foam. Used as a catalyst for polyurethane synthesis and room temperature vulcanisation of silicone rubber. It is also used as a catalytic curing agent for epoxy resins. Stannous octanoate is more catalytically active than dibutyltin laurate in curing, and if the two are used in combination, the effect is better than if they are used alone, taking into account the reaction speed and curing speed. As dibutyltin compounds are susceptible to oxidation and decomposition by oxygen and water vapour in the air, they should be stored in nitrogen protection and must be sealed to avoid high temperatures and excessive humidity to prevent a reduction in activity or failure.
Storage and transport.
Should be kept sealed and stored in a dry, cool and ventilated warehouse
Packaging.
200KG/drum Storage: Storage in a dry and cool area with proper ventilation is recommended. Please fasten the lid as soon as possible after the original packaging to prevent the mixing of other substances such as moisture from affecting the performance of the product. Store in a cool, dry place, keep the container sealed and avoid contact with oxides. Do not breathe dust and avoid contact with skin and mucous membranes. No smoking, eating or drinking in the workplace. Shower and change clothes after work. Store contaminated clothing separately and wash before use. Maintain good hygiene practices.
