  • Delayed curing silane-based curable resin system
    Patent number: 9644135
    Abstract: Method involving consolidation compositions comprising an aqueous-based fluid, a silane-based resin, a silane-based amine curing agent, and a delaying agent. The silane-based resin is an epoxy-functionalized alkoxysilane selected from the group consisting of: (3 glycidoxypropyl)trimethoxysilane, (3 glycidoxypropyl)triethoxysilane, 5,6 epoxyhexyltriethoxysilane, (3 glycidoxypropyl)methyldiethoxysilane, (3 glycidoxypropyl)methyldimethoxysilane, and (3 glycidoxypropyl)dimethylethoxysilane. The silane-based amine curing agent is selected from the group consisting of: a polyamine, a hydrophobically modified polyamine, a polyimine, a hydrophobically modified polyimine, a polyalcohol, a hydrophobically modified polyacrylamide, a hydrophobically modified polyacrylate, and any combination thereof. The delaying agent is selected from the group consisting of: methyltrichlorosilane, dimethyldichlorosilane, trimethylchlorosilane, and any combination thereof.
