Abstract:
1. An organopolysiloxane composition, comprising: (A) an organopolysiloxane having difunctional siloxane units (D units) and trifunctional siloxane units (T units), and a weight-average molecular weight of 37,000 to 140,000 in which the molar ratio (T/D) of the T units to the D units is 0.3 to 0.8; and (B) an organopolysiloxane having the difunctional siloxane units (D units) and the trifunctional siloxane units (T units), and a weight-average molecular weight of 1,000 to 60,000 in which the molar ratio (T/D) of the T units to the D units is 0.15 or less, wherein the organopolysiloxane composition has a molar ratio (B/A) of the organopolysiloxane (B) to the organopolysiloxane (A) of 1.5 to 6.5.
