Abstract
The peel strength of lightweight, liquid polysulfide-based sealants for aircraft is improved by the addition of an epoxy-terminated liquid polysulfide to the liquid polysulfide. The lightweight sealants have a specific gravity of from about 1 to about 1.3 and the amount of epoxide terminated polysulfide is from about 0.4 to about 5% of the weight of the polysulfide present in the sealant. Fillers having a specific gravity of from about 0.1 to about 2.2 are used.
