One-component, storage-stable, UV-crosslinkable organosiloxane composition
The invention relates to the use of a one-component organosiloxane composition having good storage stability at room temperature, which is crosslinkable to an elastomer by irradiation with UV light.
It is known that hydrogensiloxanes and aliphatically unsaturated compounds, especially vinyl-terminated polydimethylsiloxanes, react with one another in the presence of a hydrosilylation catalyst. For this reason, formulations comprising these constituents are customarily stored in two-component form, with one component comprising the hydrogensiloxane and a part of the aliphatically unsaturated component, and the other component comprising the hydrosilylation catalyst and the other part of the aliphatically unsaturated component. Before the reaction, the two components are mixed with one another. It would therefore be desirable if all three constituents in a mixture could be stored at room temperature without the reaction commencing, and if within this period the reaction could be initiated by irradiation with ultraviolet light or other actinic radiation.
