ABSTRACT:
A liquid silicone rubber composition comprising (A) an organopolysiloxane containing epoxy groups, (B) an organopolysiloxane containing amino groups and (C) a curing catalyst for epoxy compounds is proposed in which the compounding ratio of the component (A) to the component (B) is in the range of from 0.2 to 5.0 relative to the epoxy/amino molar ratio and which further contains optionally an organic solvent such as xylene and a silica flour. The composition is cured rapidly without the problem of catalyst poisoning even at room temperatures to be converted into a cured article with low volume resistivity and excellent antistatic performance as well as surface releasability. The composition is useful as casting materials, electric insulating materials, paint vehicles, coating materials, molding compositions and the like.
