SURFACE-TREATED INORGANIC PARTICLES, INORGANIC PARTICLE-CONTAINING COMPOSITION, THERMALLY CONDUCTIVE CURED PRODUCT, STRUCTURE, AND LAMINATE
Document Type and Number:
WIPO Patent Application WO/2023/085034
Kind Code:
A1
Abstract:
Provided are surface-treated inorganic particles from which a curable composition having good handling and storage stability, and a cured product having good thermal conductivity can be formed. Surface-treated inorganic particles (D) have: thermally conductive inorganic particles (A) having an average primary particle diameter of 0.05-100 μm; and a coating layer. The particles (A) are at least one selected from the group consisting of aluminum oxide, aluminum hydroxide, and the like, the coating layer has at least 50 mass% of a component derived from a specific silane compound, and the particles (D) have a water content of at most 0.2 mass%, and a degree of hydrophobicity of at least 35%. The amount of the silane compound is 0.05-3 mass% with respect to the particles (D).
