The cured product has excellent processability, workability, and adhesive properties or the like, and does not cause whitening and surface stickiness, etc. The cured product has excellent transparency, moisture resistance, mechanical properties, and cracking resistance, etc. The cured product, for example, may be applied as an encapsulant or an adhesive material of a semiconductor device to provide a device having high long-term reliability.
Claims17
A cured product, which is a reaction product of a mixture comprising an aliphatic unsaturated bond functional polyorganosiloxane and a compound having hydrogen atoms bound to silicon atoms, and which comprises an alkenyl group bound to silicon atoms, wherein a ratio (Ak/Si) of the number of moles of the alkenyl group (Ak) to the total number of moles of silicon atoms (Si) is in a range of 0.001 to 0.15,
- wherein the aliphatic unsaturated bond functional polyorganosiloxane shows an average unit of Formula 4:
- PaQbSiO(4-a-b)/2 [Formula 4]
- where, in Formula 4, P is an alkenyl group, Q is an epoxy group, or an alkoxy group, a and b are numbers such that a+b is in a range of 1 to 2.2, and a/(a+b) is in a range of 0.001 to 0.15.
