  • Publication number: 20190062551
    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 hydro lysable 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.

  • Patent number: 10184026
    Abstract: Vinyl-functional alcohols are silylated by reaction with a hydrolysable silyl hydride compound. The starting alcohol is heated and then combined with the silyl hydride and catalyst and allowed to heat exothermically. Cooling is applied when the conversion of vinyl groups is between 90-99%. In some embodiments, specified amounts of water are present. The cooling regimen and control of water content reduces certain side reactions, leading to greater yields to desired product.

  • Publication number: 20180244828
    Abstract: Moisture-curable polysilylated polyether compositions contain titanium (IV) catalysts and/or zinc/amidine catalyst mixtures and are devoid of or nearly devoid of tin compounds. The titanium catalysts and zinc/amide catalyst mixtures are surprisingly found to be highly effective, even when the moisture-curable silane groups of the compositions are dialkoxysilyl groups. The moisture-cured compositions are surprisingly stable when aged at high temperatures. In addition, the compositions are surprisingly storage-stable in the uncured state, particularly when the polysilylated polyethers contain aliphatic urethane groups. The polyether compositions are also preferably devoid of aminosilane adhesion promoters.
