美国采购需求：聚氨酯、聚氨酯催化剂、聚氨酯胺催化剂、胺催化剂、聚氨酯金属催化剂、二月桂酸二丁基锡 (DBTDL)

I'm interested in your products, specifically the ones related to the polyol application. I'd like to clarify whether the two items can be effectively used together in the formulation. I'm particularly curious about any potential interactions or synergies that might arise when both are combined in the system. Additionally, it would be helpful to understand how the combination might impact the overall shelf life of the polyol. Are there any specific storage conditions or considerations that we should be aware of when using these two items together? Your insights on this will greatly assist in making an informed decision. Thank you!
