摘要： An organohydrosiloxane composition comprising: a) one or more organohydrosiloxane compounds, each having at least one [—HSiR—O—] unit, wherein R═C1-C18 linear, branched, or cyclic alkyl, C1-C18 linear, branched, or cyclic alkoxy, or substituted or unsubstituted aryl, and b) an antioxidant compound shown in Formula (1) wherein the antioxidant compound is a phenolic compound and is present in a concentration from about 1 ppm to about 5,000 ppm and wherein R1 through R5 can each independently be H, OH, C1-C18 linear, branched, or cyclic alkyl, C1-C18 linear, branched, or cyclic alkoxy or substituted or unsubstituted aryl. The compositions of present invention exhibit stability and significantly extend the shelf life of organohydrosiloxane products and allow greater flexibility in handling these products in chemical processes or semiconductor manufacturing. The resulting stabilization of siloxanes prevents the possibility of complete polymerization (i.e., solidification) of product in chemical delivery lines or valves, which lowers equipment maintenance and costs and reduces time the machinery is out of production.
