Abstract
Disclosed herein is a one part moisture cure sealant which is cured under an ordinary temperature by reaction with moisture contained in the air. This sealant contains a cure accelerating catalyst of: ##STR1## in a sealing composite containing urethane prepolymer. Due to the action of this catalyst, not only the cure rate is improved but difference in the cure rate between a low-temperature/low-humidity season and a high-temperature/high-humidity season is reduced. This sealant is also excellent in storage stability.
