Title:
SILICONE RESIN-COVERED SILICONE ELASTOMER PARTICLES, ORGANIC RESIN ADDITIVE, AND OTHER USES
Document Type and Number:
WIPO Patent Application WO/2019/124418
Kind Code:
A1
Abstract:
[Problem] Provided are: silicone resin-covered silicone elastomer particles having excellent stress relaxation properties and dispersibility to organic resins and also having excellent handleability/workability due to low scattering properties at the time of blending; and uses, such as an organic resin additive, an organic resin, a coating composition or coating agent composition, and a cosmetic composition, that contain said particles. [Solution] Disclosed are silicone resin-covered silicone elastomer particles, wherein: a portion or the entirety of the surface of the particles is covered by a silicone resin constituted by a siloxane unit represented by SiO4/2; and the particles have a structure in which at least two silicon atoms within the silicone elastomer particle are cross-linked by a C4-20 silalkylene group. Also disclosed is a use of the silicone elastomer particles.
