Patent ID: 10808124

Abstract:
This gel-form composition contains (A) an organoalkoxysilane of the following formula and/or a partially hydrolyzed condensate of the organoalkoxysilane, R1aSi(OR2)4-a (R1 and R2 are monovalent hydrocarbon groups, and a is 1, 2, or 3), (B) an aluminum dicarboxylate of the following formula (R3COO)2Al(OH) (R3 is a monovalent hydrocarbon group), (C) a C6-24 fatty acid, (D) a C6-30 dicarboxylic acid, and (E) an aluminum oligomer and/or aluminum alkoxide selected from aluminum oxide organoxides and aluminum oxide acylates. It is thereby possible to: obtain a water absorption inhibitor that imparts an excellent water absorption-inhibiting property to the surfaces of porous materials; and provide a method for imparting a water absorption-inhibiting property by applying the water absorption inhibitor to the surface of a porous material, and a porous material that is surface-treated by the water absorption inhibitor.
