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.

Various embodiments disclosed relate to polysulfide or polythioether sealant composition including glycol organic acid esters. The sealant composition can include a first component including a liquid that is a polysulfide, a polythioether, a copolymer thereof, or a combination thereof. The sealant composition can also include a second component that includes one or more glycol di((C.sub.1-C.sub.20)hydrocarbyl)carboxylate esters, wherein at each occurrence the (C.sub.1-C.sub.20)hydrocarbyl is independently substituted or unsubstituted. The second component can also include an oxidizing agent.
