Purpose:
For organic synthesis.
Stannous octoate is a white or light yellow-brown paste, sometimes called stannous octoate. Soluble in petroleum ether, insoluble in water. It is the basic catalyst for the production of polyurethane foam. It is mainly used for the gelation reaction of polyether-polyurethane foaming. It can also be used as an antioxidant for urethane foam. Used as a catalyst for polyurethane synthesis and room temperature vulcanization of silicone rubber. It is also used as a catalyst type curing agent for epoxy resin. The catalytic activity of stannous octoate is greater than that of dibutyltin dilaurate during curing. If the two are used in combination, the effect will be better than when used alone, and it can take into account the reaction speed and curing speed. Since divalent tin compounds are easily oxidized and decomposed by oxygen and water vapor in the air, they must be used for nitrogen protection during storage and must be sealed to avoid high temperature and excessive humidity to prevent activity degradation or failure.
Storage and transportation:
