Abstract
A one-part pourable sealant that is thermosetting, non-shrinking, and capable of quickly curing in a closed cavity to a depth of at least two inches includes a silyl-terminated polymer, a hygroscopic plasticizer present in an amount that is effective to promote rapid and deep curing, and a catalyst for promoting curing of the silyl-terminated polymer. The sealer composition is useful in a method of forming a seal around a roof penetration. The method includes dispensing the sealer composition into a pitch pocket formed around a roof penetration and allowing the sealer composition dispensed into the pitch pocket to cure by exposure to moisture in the air.
