摘要:
A gel has improved thermal stability and is the hydrosilylation reaction product of (A) an organopolysiloxane having an average of at least 0.1 silicon-bonded alkenyl group per molecule and (B) a cross-linker having an average of at least 2 silicon-bonded hydrogen atoms per molecule. (A) and (B) react via hydrosilylation in the presence of (C) a hydrosilylation catalyst and (D) a phthalocyanine. The (D) phthalocyanine is present in an amount of from about 0.05 to about 30 weight percent based on a total weight of (A) and (B). The gel has a hardness of less than about 1500 grams as measured after heat ageing at 225 °C for 1000 hours that is calculated as a weight required to insert a TA-23 probe into the gel to a depth of 3 mm.
摘要(中):
凝胶具有改善的热稳定性,并且是(A)每分子平均具有至少0.1个硅键合的烯基的有机聚硅氧烷的氢化硅烷化反应产物,(B)平均具有至少2个硅键合的交联剂 氢原子每分子。 在(C)氢化硅烷化催化剂和(D)酞菁的存在下,(A)和(B)通过氢化硅烷化反应。 基于(A)和(B)的总重量,(D)酞菁的存在量为约0.05至约30重量%。 凝胶的硬度小于约1500克,在225℃下热老化1000小时后测量,其计算为将TA-23探针插入凝胶至3mm深度所需的重量。
