    摘要： The invention pertains to a method of passivating direct process solids and to passivated and quenched compositions resulting from said method. The method of passivating direct process solids according to the invention comprises combining direct process solids with a passivating composition comprising clay, base, and water. The passivated composition of the invention comprises direct process solids and a passivating composition comprising clay, base, and water. The quenched composition of the invention comprises the passivated composition, wherein the passivated composition has been held for a sufficient period of time for the reactive species from the direct process solids to be substantially quenched and/or oxidized.

    摘要： The present disclosure provides methods of making organosiloxane polymer compositions from hydrosilylation curable compositions comprising at least the components (a) and (b) and at least one of components (c) and (d): (a) an organosiloxane resin material comprising aliphatic unsaturation; and (b) an organosiloxane crosslinker comprising multiple silicon atom-bonded hydrogen atoms (e.g., an “SiH siloxane”); in combination with at least one of (c) at least one organosiloxane comprising at least two silicon atom-bonded hydrogen atoms; and (d) at least one organosiloxane comprising at least two silicon atom-bonded hydrocarbyl groups comprising aliphatic unsaturation (e.g., a “di-vinyl functional siloxane”). Such hydrosilylation curable compositions have, in some instances, significantly faster cure speed, relative to their condensation curable counterparts. A faster cure speed can be important for encapsulating electronic devices, such as light-emitting diode (LED) chip devices, including devices having tall structures.

    摘要： The present invention relates to a curable silicone composition comprising: (A) an organopolysiloxane having at least two alkenyl groups and at least one aryl group in a molecule, (B) an organopolysiloxane having at least two silicon atom-bonded hydrogen atoms in a molecule, (C) an organopolysiloxane having at least one aryl group in a molecule and containing a metal atom selected from the group consisting of V, Ta, Nb and Ce, and (D) a hydrosilylation-reaction catalyst. The present invention can provide the curable silicone composition, which does not develop a crack by thermal aging and further can form a cured material that exhibits less yellowing. Abstract (as published by WIPO) The present invention pertains to a curable silicone composition comprising at least: (A) an organo-polysiloxane having, per molecule thereof, two or more alkenyl groups and one or more aryl groups; (B) an organo-polysiloxane having, per molecule thereof, two or more silicon-bonded hydrogen atoms; (C) an organo-polysiloxane having, per molecule thereof, one or more aryl groups, and a metal atom selected from a group consisting of V, Ta, Nb and Ce; and (D) a hydrosilation reaction catalyst. The present invention is capable of providing a curable silicone composition capable of forming a cured product which exhibits minimal yellowing, without producing cracks caused by thermal aging.

    摘要： A method for preparing an article includes applying a first composition on a substrate to form a first layer, and applying a curing condition to a target portion without applying the curing condition to a non-target portion of the first layer to form a first contrast layer. A second composition is then applied on the first contrast layer to form a second layer, and a curing condition is applied to a target portion without applying the curing condition to a non-target portion of the second layer and first contrast layer to form a second contrast layer. A third composition can optionally be applied and cured on the second contrast layer to form a third contrast layer having a cured and uncured portion in the same manner. The uncured portions of these contrast layers are then selectively removed to prepare the article.
