Estimating the term…
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.
A curable sealant composition comprising:
(canceled)
A method of forming a curable sealant composition comprising a polysulfide having an —SH group, a compound having at least one carbon-carbon double bond, an allylborane amine catalyst, and a metal oxide catalyst, said method comprising the steps of:
An article comprising a substrate and cured sealant disposed thereon, wherein said cured sealant comprises the reaction product of a polysulfide having an —SH group and a compound having at least one carbon-carbon double bond reacted in the presence of an alkylborane amine catalyst and a metal oxide catalyst.
