Silicone-Acrylic Fine Particles: SOLIOSTAR™ RA Series Organic-Inorganic Hybrid Fine Particles

Basic Information

SOLIOSTAR™ RA are organic-inorganic hybrid-type, monodispersed, spherical fine particles with a sharp particle size distribution.
In addition to being able to control a uniform particle diameter, by using various types of organic and inorganic components in an arbitrary ratio, it is also possible to control the refractive index and degree of hardness, as well as design various particle surface states. This enables SOLIOSTAR™ RA to be used as a light diffusion agent for liquid crystal displays (LCD) of televisions and computers.
