Patent ID: 7781513

Claim:
A two-part moisture-curable resin composition which comprises: a) a first part substantially free of moisture comprising: (1) moisture-curable silylated resin obtained by the silylation of at least one resin selected from the group consisting of polyether polyol (i), polyester polyol (ii), hydroxyl-terminated polybutadiene (iii), hydroxyl terminated or isocyanate-terminated polyurethane prepolymer (iv) derived from at least one of polyether polyol (i), polyester polyol (ii) or hydroxy-terminated polybutadiene (iii), amine-terminated or isocyanate-terminated polyurethane-polyurea prepolymer and/or polyurea prepolymer (v) derived from polyamine, and olefinically unsaturated resin (vi); and, (2) optionally, one or more additional components selected from the group consisting of plasticizer, solvent, thixotropic agent, particulate material, moisture scavenger, isocyanate scavenger, crosslinker, adhesion promoter, U.V. stabilizer and antioxidant; and, b) a second part comprising: (1) water in an amount sufficient to cure moisture-curable silylated resin (a)(1); (2) at least one plasticizer and/or particulate material, (3) nonionic surfactant (b)(3) in an amount sufficient to provide a stable emulsion of plasticizer (b)(2), if present, and a stable suspension of particulate material (b)(2), if present, wherein non-ionic surfactant (b)(3) is selected from the group consisting of polyethylene glycol, polypropylene glycol, copolymer of ethylene oxide and propylene oxide, ethoxylated castor oil, oleic acid ethoxylate, alkylphenol ethoxylate, copolymer of silicone and polyether and mixtures of the foregoing; and (4) optionally, one or more additional components selected from the group consisting of solvent, thixotropic agent, pH adjuster, U.V. stabilizer and antioxidant, provided, the first part and/or the second part further comprises catalyst (c) for the condensation reaction of hydrolyzed moisture-curable silylated resin (a)(1).
