在由(A)至少有两个硅与链烯烃基团连接的有机聚硅氧烷、(B)至少有两个S iH基团的有机氢聚硅氧烷和(C)氢化硅烷化催化剂构成的加成型硅橡胶胶粘剂胶料中,加入(D)在25℃下粘度为5～10 000 mPa·s的(甲基)丙烯酰氧基改性的线性或环状有机聚硅氧烷和(E)锆化合物,即使通过简短的加热也可形成一定的粘合强度,并且长期热试验之后的褪色程度最小。
In the case of (A) an organopolysiloxane having at least two silicon attached to an alkene group, (B) an organohydrogenpolysiloxane having at least two SiH groups, and (C) a hydrosilylation catalyst (D) a (meth) acryloyloxy-modified linear or cyclic organopolysiloxane having a viscosity of 5 to 10,000 mPas at 25C and E) zirconium compounds, a certain adhesive strength can be formed even by a short heating, and the degree of discoloration after the long-term heat test is minimized.
