Zusammenfassung:Various embodiments disclosed related to UV-curable silicone composition, cured products thereof, and methods of using the same. Various embodiments provide a shear-thinning UV-curable silicone composition. The composition can include (A) a mercapto-functional polyorganosiloxane having the unit formula [(CH3)3SiO1/2]x[(CH3)2SiO]y[R(CH3)SiO]z wherein x is about 0.01 to about 0.1, y is about 0 to about 0.94, z is about 0.05 to about 0.99, and at each occurrence R is independently a mercapto(C1-30)hydrocarbyl group. The composition can include (B) at least one of (B1) a polyorganosiloxane comprising at least two aliphatic unsaturated carbon-carbon bonds, and (B2) an organic molecule comprising at least two aliphatic unsaturated carbon-carbon bonds; the composition can include (C) a filler. The composition can also include (D) a photoinitiator.
