Abstract: A dual-curable sealant composition includes a polysulfide having an —SH group, a metal oxide catalyst, and an alkylborane amine catalyst. A cured sealant is also formed from the dual-curable sealant composition. Moreover, a dual-cured sealant is formed that includes the polymerization product of the polysulfide reacted in the presence of the metal oxide catalyst and the alkylborane amine catalyst. Further, a dual-curable sealant system includes a first component including the polysulfide and the alkylborane amine catalyst and a second component including the metal oxide catalyst. An article is formed that includes a substrate and the cured sealant disposed on the substrate. Even further, a method of forming the dual-curable sealant composition includes the steps of providing the polysulfide, the alkylborane amine catalyst, and the metal oxide catalyst, and combining the polysulfide, the alkylborane amine catalyst, and the metal oxide catalyst to form the dual-curable composition.

Abstract: A curable sealant composition includes a polysulfide having an —SH group, a compound having at least one carbon-carbon double bond, and an alkylborane amine catalyst. A cured sealant is formed from the curable sealant composition, wherein the cured sealant includes the polymerization product of the polysulfide and the compound having the at least one carbon-carbon double bond reacted in the presence of the alkylborane amine catalyst. Furthermore, a curable sealant system includes a first component including the polysulfide and the alkylborane amine catalyst and a second component including the compound having the at least one carbon-carbon double bond. Moreover, an article includes a substrate and the cured sealant disposed on the substrate. The curable sealant composition is formed using a method including the steps of providing and combining the polysulfide, the alkylborane amine catalyst, and the compound having the at least one carbon-carbon double bond, to form the curable composition.
