Abstract
A uniformly premixed sealant is provided as a frozen preform that upon warming cures in the preform shape. The storage of the preformed sealant formulation under cold conditions arrests the activity of cure catalysts and accelerators mixed therethrough. A release film is provided to avoid contact with the preformed sealant during application to a substrate. The preformed sealant is particularly well suited for use in aerospace applications.
