Patent ID: 7329464

Claim:
A peroxide curable silicon adhesive composition comprising: 20 to 80 parts by weight of a diorganopolysiloxane (A) represented by any one of the following formulae R 2 3 SiO—(R 2 2 SiO) p —SiR 2 3 R 2 2 (HO)SiO—(R 2 2 SiO) p —SiR 2 2 (OH) where R 2 may be the same with or different from each other, and R 2 is a hydrocarbon group having 1 to 10 carbon atoms, and p is such a number that a viscosity at 25 degrees C. of component (A) is 500 mPa·s or higher, 80 to 20 parts by weight of a polyorganosiloxane (B) comprising R 1 3 SiO 0.5 unit and SiO 2 unit in a molar ratio of the R 1 3 SiO 0.5 unit to the SiO 2 unit of from 0.6 to 1.0, wherein R 1 is a monovalent hydrocarbon group having 1 to 10 carbon atoms, 0.01 to 1.0 part by weight, based on a total of (A) and (B) of 100 parts by weight, of a hindered amine compound (C) having the moiety represented by the following formula wherein R is a monovalent hydrocarbon group having 1 to 6 carbon atoms, and 0.1 to 5.0 parts by weight, based on a total of (A) and (B) of 100 parts by weight, of an organic peroxide (D).
