A method for molding shaped silicone elastomeric articles from room temperature curable silicone compositions, which are practically not suited to being processed using extrusion techniques, is provided. The method enables the room temperature curable silicone composition to cure in a predefined shape () into which it is introduced to form a shaped silicone elastomeric article. The articles may be, for the sake of example, suitable for use as spacers for insulating glass units (IGUs).

Method for making elastomeric articles

A method for producing an optical silicone assembly is disclosed. The method comprises the steps of: i) treating a surface of a substrate with an optically clear silicone adhesive composition; ii) placing the substrate obtained by step i) into a mold; iii-a) injecting an optically clear moldable silicone composition into the mold, and/or iii-b) overmolding the optically clear moldable silicone composition onto the substrate; and then iv) heating the optically clear moldable silicone composition to form the optical silicone assembly. The optical silicone assembly produced by the method of this disclosure is characterized by excellent adhesion of an optical silicone product to various types of substrates.

Method for producing optical silicone assembly, and optical silicone assembly produced thereby

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.
