Abstract
A moisture-curable composition is shown and described herein. The moisture-curable composition comprises a moisture-curable resin and a moisture scavenger selected from a cyanoalkylalkoxysilane. The inclusion of the cyanoalkylalkoxysilane in the moisture-curable composition has been found to effectively scavenge moisture and control the rate of curing and viscosity increase in the composition.
Claims20
A moisture-curable composition comprising:
- (a) a moisture-curable resin comprising a polymer that is reactive with water, wherein the moisture-curable resin (a) is selected from a silylated polyol;
- a silylated polyether;
- a silylated polyurethane;
- a silane-containing copolymer derived from the copolymerization of an ethylenically unsaturated silane selected from a vinylsilane, an allylsilane, a methallylsilane, an acryloxyalkylsilane, a methacryloxyalkylsilane, and an ethylenically unsaturated monomer selected from an olefinic hydrocarbon, an acrylic acid, a methacrylic acid, an acrylate ester, a methacrylate ester, an ethylenically unsaturated dicarboxylic acid, and/or an anhydride of the ethylenically unsaturated monomer, oligomers, and/or a polymer possessing ethylenic unsaturation;
- a combination of two or more thereof;
- and
- (b) a moisture scavenger selected from a cyanoalkylalkoxysilane.
