A curable silicone composition for forming a microchannel, a cured product thereof, and a microchannel device and a method for producing the same.

摘要

PROBLEM TO BE SOLVED: To provide a curable silicone composition which exhibits excellent mechanical properties and transparency after curing and has a hydrophilic surface. The following formula: -RO- (C2H4O) m (C3H6O) nX (R is an alkylene group of C2-6, X is an alkyl group of H or C1-3, m is 1-10, n is A curable silicone composition 2 for forming a microchannel, comprising an organosiloxane oligomer having at least one polyether group represented by 0-2, m> n) in the molecule, wherein X is hydrogen. When it is an atom, the content of the organosiloxane oligomer is 0.3 to 1.0% by mass with respect to the curable silicone composition, and when X is an alkyl group having 1 to 3 carbon atoms, A curable silicone composition in which the content of the organosiloxane oligomer is 0.3 to 1.5% by mass with respect to the curable silicone composition.
