Abstract

A siloxane resin and photoelectric device employing the same are provided. The siloxane resin composition includes (a) 45-87 parts by weight of a first siloxane compound represented by Formula (I), wherein each R 1 is independently C 1-3 alkyl group, and n is an integer from 2 to 15;

(b) 5-35 parts by weight of a second siloxane compound represented by Formula (II), wherein each R 2 and R 3 are independently C 1-3 alkyl group; each R 4 is independently C 1-3 alkyl group, or epoxy group; x≧1, y≧2, and x/y is from about 0.1 to 3; and

(c) 2-20 parts by weight of a third siloxane compound represented by Formula (III), wherein each R 5 is independently C 1-3 alkyl group, and the sum of the first siloxane compound, the second siloxane compound, and the third siloxane compound is 100 parts by weight

First claim

What is claimed is:

1. A siloxane resin composition, comprising:
(a) 45-87 parts by weight of a first siloxane compound represented by Formula (I)

wherein each R 1 is independently C 1-3 alkyl group, and n is an integer from 2 to 15;
(b) 5-35 parts by weight of a second siloxane compound represented by Formula (II)

wherein each R 2 and R 3 are independently C 1-3 alkyl group; each R 4 is independently C 1-3 alkyl group, or epoxy group; x≧1, y≧2, and x/y is from 0.1 to 3; and
(c) 2-20 parts by weight of a third siloxane compound represented by Formula (III)

wherein each R 5 is independently C 1-3 alkyl group,
wherein the sum of the first siloxane compound, the second siloxane compound, and the third siloxane compound is 100 parts by weight.

2. The siloxane resin composition as claimed in claim 1 , further comprising:
(d) 20-50 parts by weight of a curing agent.

3. The siloxane resin composition as claimed in claim 2 , wherein the curing agent is an anhydride curing agent.

4. The siloxane resin composition as claimed in claim 3 , wherein a cured product of the siloxane resin composition has a visible light transmittance greater than 90%.

5. The siloxane resin composition as claimed in claim 2 , wherein the curing agent is aliphatic amine curing agent, cyclic aliphatic amine curing agent, aromatic-aliphatic amine curing agent, phenolic curing agent, or a combination thereof.

6. The siloxane resin composition as claimed in claim 1 , further comprising:
(e) 0.1-1 parts by weight of a reaction accelerator.

7. The siloxane resin composition as claimed in claim 6 , wherein the reaction accelerator comprises quaternary phosphate, amine, or a combination thereof.

8. The siloxane resin composition as claimed in claim 1 , further comprising:
(f) 0.1-5 parts by weight of an additive.

9. The siloxane resin composition as claimed in claim 8 , wherein the additive comprise a reaction accelerator, an adhesion promoter, antioxidant, defoamer, leveling agent, stabilizer, or a combination thereof.

10. An optoelectronic device, comprising:
an optoelectronic element; and
a siloxane resin material layer disposed on the optoelectronic element, wherein the siloxane resin material layer is made from the siloxane resin composition as claimed in claim 1 .

11. The optoelectronic device as claimed in claim 10 , wherein the optoelectronic element comprises a light-emitting diode, laser diode, or optical receiver.
