Abstract
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, a polyene comprising a polyvinyl ether and/or a polyallyl compound, and a hydroxy-functional vinyl ether. Related sealant compositions are also disclosed.
