ADDITION-CURABLE SILICONE RUBBER COMPOSITION AND CURED PRODUCT THEREOF

摘要

An addition curable silicone rubber composition is provided to reduce evaporation of low-molecular weight siloxane components from a cured product, and to obtain a cured product capable of preventing generation of turbidness. An addition curable silicone rubber composition comprises: (A) 100 parts by weight of an organopolysiloxane containing at least two alkenyl groups bonded to Si per molecule; (B) 0.3-20 parts by weight of an organohydrogenpolysioxane having at least two hydrogen atoms bonded to Si (SiH groups) per molecule; and (C) a catalytically effective amount of an addition catalyst. The composition comprises 0.5 wt% or less of an organopolysiloxane having a polymerization degree of 10 or less and containing at least one SiH group per molecule.
