    摘要: This aqueous composition contains: a silanol compound having an imidazolidinone group represented by general formula (1); and a condensate of the silanol compound. The content of an alcohol is less than 5 mass% relative to the content of the silanol compound and the condensate of the silanol compound. The aqueous composition suppresses the generation of alcohols, suppresses excessive condensation of the silanol compound, prevents an increase in molecular weight over time, and yields a colorless transparent aqueous solution.

    (In the formula, R1 denotes a halogen atom or a methyl group, R2 denotes an unsubstituted divalent hydrocarbon group having 1-8 carbon atoms, and n denotes an integer between 0 and 2.)

    摘要: The present invention is an isocyanate group-containing organosilicon compound shown by the following general formula (1), and having three or more R 2 groups per molecule and a viscosity at 25°C of 100 mm 2 /s or less. This provides an organosilicon compound which has three or more isocyanate groups per molecule, and which is suitable as a crosslinking agent, low in viscosity, and excellent in handleability. R 1 a R 2 b SiO (4-a-b)/2 (1), where each R 1 is identical to or different from one another, represents a monovalent alkyl group having 1 to 10 carbon atoms, a fluorine-substituted alkyl group, a monovalent aryl group having 6 to 10 carbon atoms, or a monovalent aralkyl group having 7 to 10 carbon atoms, and has no aliphatic unsaturated group; and R 2 represents an organic group shown by a formula - CH 2 CH 2 Si(CH 3 ) 2 OSi(CH 3 ) 2 CH 2 CH 2 CH 2 NCO.
