Used as a catalyst for polyurethane synthesis and room temperature vulcanization of silicone rubber. Also used as epoxy resin catalyst curing agent. During curing, stannous octoate has higher catalytic activity than dibutyltin dilaurate. If the two are used in combination, the effect is better than when they are used alone, and the reaction speed and curing speed can be taken into account. Since the divalent tin compound is oxidized and decomposed by oxygen and water vapor in the air, it must be used for nitrogen protection during storage, and must be sealed to avoid high temperature and excessive humidity to prevent activity decline or failure.
