    摘要: One-part moisture curable sealant compositions and methods of making the same are provided. The composition includes a silane-terminated polythioether component and a catalyst. The silane-terminated polythioether component and catalyst are isolated from moisture to prevent curing. The composition is stable against curing at ambient temperature and under conditions substantially free of moisture. When the composition is applied to a substrate and exposed to moisture, the composition cures to form a sealant. A method of making a sealant composition includes reacting a mercapto-terminated polythioether with a compound having a silane group to form a silane-terminated polythioether. The silane-terminated polythioether is then combined with a catalyst and isolated from moisture to prevent curing. Lastly, the composition is applied to a substrate and exposed to moisture which allows the composition to cure to form a sealant.
