摘要:
Disclosed are polyfunctional sulfur-containing epoxies and compositions containing polyfunctional sulfur-containing epoxies. The polyfunctional sulfur-containing epoxies may be used as a curing agent and combined with polythioethers and/or polysulfides used to provide high elongation sealants useful in aerospace applications.

摘要:
Disclosed are methods for making a cured sealant. The methods include depositing an uncured sealant composition on a substrate and exposing the uncured sealant composition to actinic radiation to provide a cured sealant. The uncured sealant composition includes a thiol-terminated polythioether and a polyene comprising a polyvinyl ether and/or a polyallyl compound. Related sealant compositions are also disclosed.
