Abstract:
An addition-curable silicone rubber composition comprising:(A) an organopolysiloxane containing in one molecule at least two alkenyl groups bonded to silicon atoms, represented by the average compositional formula (1):R.sup.1.sub.a R.sup.2.sup.b SiO.sub.(4-a-b)/2wherein R.sup.1 represents a substituted or unsubstituted monovalent hydrocarbon group containing no aliphatic unsaturated bond; R.sup.2 represents an alkenyl group; and a is a number ranging from 0.96 to 2.00, b is a number ranging from 0.0001 to 0.5, and a and b satisfy a+b=1.90 to 2.04;(B) an organohydrogenpolysiloxane containing in one molecule at least two hydrogen atoms bonded to silicon atoms, represented by the average compositional formula (2):R.sup.3.sub.c H.sub.d SiO.sub.(4-c-d)/2wherein R.sup.3 represents a substituted or unsubstituted monovalent hydrocarbon group containing no aliphatic unsaturated bond; and c is a number ranging from 0.70 to 2.0, d is a number ranging from 0.005 to 1.0, and c and d satisfy c+d=0.8 to 3.0;(C) a platinum catalyst; and(D) a (meth)acrylate compound having a structure represented by the formula: ##STR10##wherein R stands for a hydrogen atom or a methyl group therein and having a melting point of 40.degree. C. or above.
