Title:
TWO-PACK TYPE CURABLE COMPOSITION SET, CURED PRODUCT AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/190439
Kind Code:
A1
Abstract:
The present invention provides a two-pack type curable composition set which comprises: a first agent that contains a copolymer A1, a vinyl-modified organopolysiloxane B1, a thermally conductive filler C1 and an addition reaction catalyst D1; and a second agent that contains a copolymer A2, a vinyl-modified organopolysiloxane B2, a thermally conductive filler C2 and a hydrosilyl-modified organopolysiloxane E2. With respect to this two-pack type curable composition set, the copolymer A1 and the copolymer A2 each have a (meth)acrylic monomer unit α that has a carboxy group, a (meth)acrylic monomer unit β that has a tertiary amino group, and a (meth)acrylic monomer unit γ that has a siloxane skeleton; and if the first agent and the second agent are mixed with each other in equal volumes, the time necessary for the mixture to achieve a loss tangent tanδ of less than 0.20 is 24 hours or less after the mixing.
