Study of Room Temperature Moisture Curable Silylated Polyether

Moisture curable silylated polyether was synthesized through corresponding urethane prepolymer.Influence of temperature and time on reaction and influence of various NCO/OH ratios and molecular weights of polyether on mechanical property of elastomer were studied.Comparison with mechanical properties of several kinds of sealants available on the market showed that the silylated polyether had good properties.
