Curable resin composition and cured product thereof, encapsulant, and semiconductor device |
摘要 |
Provided is a curable resin composition capable of forming a cured product that has excellent heat resistance and transparency and, in particular, offers excellent barrier properties to a corrosive gas. The curable resin composition according to the present invention includes a polyorganosiloxane (A), an isocyanurate compound (B), and a silane coupling agent (C). The polyorganosiloxane (A) is an aryl-containing polyorganosiloxane. The polyorganosiloxane (A) preferably includes a polyorganosiloxane having a number-average molecular weight (Mn) of 500 to 4000 as determined by gel permeation chromatography and calibrated with a polystyrene standard. |

1. A curable resin composition comprising:
a polyorganosiloxane (A) excluding a silsesquioxane; an isocyanurate compound (B); and a silane coupling agent (C), the polyorganosiloxane (A) being an aryl-containing polyorganosiloxane, the aryl-containing polyorganosiloxane having: a number-average molecular weight (Mn) of from 500 to 4000 as determined by gel permeation chromatography and calibrated with a polystyrene standard; and a molecular-weight dispersity (Mw/Mn) of from 0.95 to 4.00, where the aryl-containing polyorganosiloxane has a weight-average molecular weight of Mw and a number-average molecular weight of Mn as determined by gel permeation chromatography and calibrated with a polystyrene standard, the polyorganosiloxane (A) comprising:
a polyorganosiloxane (A1) comprising an aliphatic carbon-carbon double bond; anda polyorganosiloxane (A2) comprising a Si—H bond, the polyorganosiloxane (A) comprising 50 percent by weight or more of the polyorganosiloxane (A2) comprising a Si—H bond based on the total amount (100 percent by weight) of the polyorganosiloxane (A), and the isocyanurate compound (B) comprising
an isocyanurate compound represented by Formula (1):wherein Rx, Ry, and Rz are each, identically or differently, selected from a group represented by Formula (2) and a group represented by Formula (3), where at least one of Rx, Ry, and Rz is the group represented by Formula (3):wherein R1 and R2 are each, identically or differently, selected from hydrogen and C1-C8 straight or branched chain alkyl. |
