Abstract
Moisture-curable resin compositions include a mixture of one or more polysilylated of ethers and one or more polyether monosilanes. The polyether monosilanes have one hydrolysable silane group per molecule, and the hydrolysable silane group has at least two hydrolysable substituents. The polyether monosilane is an effective plasticizer and viscosity reducer. Despite the presence of the polyether monosilane, the resins compositions cure to form cured sealants having useful tensile and elongation properties.
