Abstract
This invention relates generally to sealants for insulating glass units. More specifically, this invention is a one-component, hot applied, chemically curing sealant for edge sealing insulating glass units. The sealant contains a thermoplastic hot melt resin blended with an atmospheric curing resin. The hot melt resin functions as the meltable component during the initial application, and supplies strength immediately upon cooling. The polymer phase then begins to cure by reaction with atmospheric oxygen and/or moisture to form a cross-linked thermoset elastomer which is temperature resistant. At this point, the hot melt resin functions as an inert plasticizer within the cured polymer phase. The sealant of the present invention may additionally include plasticizers, fillers, pigments, catalysts and the like.
