    Abstract: The disclosed provides a machine of paste shrinkage and expansion for timely monitoring a paste shrinkage in a Z direction during a UV curing process and for obtaining a change rate of a paste in a Z direction after a certain process. The machine comprises: a bottom substrate; a top substrate which is transparent and configured to be placed on the paste so that the paste is sandwiched between a top surface of the bottom substrate and a bottom surface of the top substrate, wherein the top surface of the bottom substrate and the bottom surface of the top substrate are provided with first and second reflecting layers, respectively, and define a thickness of the paste; a platform for supporting the bottom substrate; a plurality of pressing clamps configured for securing the bottom substrate on the platform in the Z direction; a plurality of pushing clamps configured for securing the bottom substrate in radial and circumferential directions; a plurality of UV sources positioned uniformly around the paste; and a sensor configured for measuring the thickness of the paste. The bottom substrate and the platform comprise a substrate dial and a platform dial, respectively, and the bottom substrate has a profile consistent with the platform dial. The disclosed provides methods for timely monitoring a paste shrinkage in a Z direction during a UV curing process and for obtaining a change rate of a paste in a Z direction after a certain process.

    Abstract: Transparency, mechanical strength and resistance against heat as well as photo-degradation of a silicone-based curable composition shall be improved. This is achieved by providing a curable composition comprising: (A) at least one organopolysiloxane represented by the composition formula (1): (R 1 3 Si0 1/2 ) a (R 1 2 Si0 2/2 ) b (R 1 R 2 SiO 2/2 ) c (R 1 SiO 3/2 ) d (R 2 SiO 3/2 ) e (R 1 2 R 2 SiO 1/2 ) f (1), wherein each R1 independently represents a monovalent organic group having 1 to 20 carbon atoms or an OH group with the proviso that at each silicon-atom bearing no R 2 at least one R1 represents a monovalent organic group having 1 to 20 carbon atoms, each R 2 independently represents a methacryloxyalkyl group having 5 to 20 carbon atoms and a, b, c, d, e, f each represent the fraction of the number of the respective units based on the number of all units of the organopolysiloxane and satisfy a ≥ 0, b ≥ 0, c ≥ 0, d ≥ 0, e ≥ 0, f ≥ 0 and also satisfy c+e > 0 and a+b+c+d+e+f = 1; and (B) at least one curing catalyst. A transparent product can be obtained after curing of the aforementioned silicone composition that exhibits excellent discoloration resistance and good mechanical strength. Therefore, the product is ideal for encapsulation of LED (light emitting device) elements.
