Abstract

See full text

Sealant systems that are pre-applied to a part to be sealed include a layer of an uncured moisture-curable sealant and a frangible barrier coating applied over the uncured moisture-curable sealant. During assembly, the barrier coating breaks to expose the moisture-curable sealant to moisture to initiate the curing reaction. The moisture-curable sealant systems are suitable for aerospace applications and include sulfur-containing prepolymers. Various curing chemistries can be used.
