Isocyanate group-containing organosilicon compound and method for producing isocyanate group-containing organosilicon compound

Abstract

An isocyanate group-containing organosilicon compound shown by the following general formula (1), and having three or more R2 groups per molecule and a viscosity at 25° C. of 100 mm2/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. R1aR2bSiO(4−a−b)/2 (1), where each R1 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 R2 represents an organic group shown by a formula —CH2CH2Si(CH3)2OSi(CH3)2CH2CH2CH2NCO.
