摘要：
Compositions comprising sulfur-containing prepolymers such as polythioether prepolymers, polyepoxides, and a blocked 1,8-diazabicyclo[5.4.0]undec-7-ene bicarbonate catalyst useful as aerospace sealants are disclosed. The compositions exhibit extended working time and the curing rate can be tailored for specific applications.
