  • Patent number: 11155711
    Abstract: A composition is disclosed, which comprises (I) an aryl component; (II) a methyl component; and (III) a hydrosilylation catalyst. The (I) aryl component comprises (A) an organopolysiloxane and (B) an organohydrogenpolysiloxane. Similarly, the (II) methyl component comprises (A) an organopolysiloxane and (B) an organohydrogenpolysiloxane. A method of preparing the composition is also disclosed. Further, a method of preparing an article, e.g. a light diffuser, and a lighting device comprising the light diffuser are disclosed. Finally, a method of diffusely transmitting light with the light diffuser is disclosed.
    Type: Grant
