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.

Abstract: Electronic devices operate in an analog world and their circuitry is subject to non-linear environmental effects that can cause operational problems. Selecting components for a design for a capacitor-charging circuit that incorporates a current-limiting resistor and uses non-linear power supplies, either means having to test every possible combination of elements, and suffering a resultant ‘combinatorial explosion’ as complexity increases, or choosing to over-engineer against untested surprise failure points. Doing the latter in a cost-efficient manner through a min/max/log-set testing series also enables use of non-linear power supplies whose parameters are not known due to competitive or trade secret protective efforts by their manufacturers.

Abstract: An attribute design database system provides for inventory management, order process management and design management. The system operates in a telecommunications management network provisioning environment. It provides a physical network management system that includes various telecommunications network management tools. Graphical user interface facilitates the user's navigation of the database system to enable the same person to have access to and the ability to modify information in regards to inventory management, design management and order management for the network.
