Document Type and Number:
Japanese Patent JP6930815
Kind Code:
B2
Abstract:
[Problem] Provided are a curable particulate silicone composition having hot-melt properties, excellent handling workability and curing characteristics, high light reflectance in the visible wavelength region, and excellent flexibility and toughness at a temperature of from room temperature to a high temperature of about 150°C., and use thereof.[Resolution Means] A curable particulate silicone composition, includes (A) hot-melt silicone fine particles having a softening point of 30°C. or higher and having a hydrosilylation reactive group and/or a radical reactive group; (B) an inorganic filler substantially free of coarse particles having an average particle diameter of 5 µm or more (fine particles); and (C) a curing agent, wherein when cured, the curable particulate silicone composition provides a cured product that has: a storage modulus (G') at 25°C. of 2000 MPa or less, and a storage modulus (G') at 150°C. of 100 MPa or less, and a spectral reflectance of 90% or more at a wavelength of 450 nm, preferably 700 nm, at a thickness of 100 µm, and use thereof.
