Beschreibung
Zusammenfassung:	A silicone rubber composition comprising (A) 100 parts by weight of a polyorganosiloxane having, per molecule, at least two structural units represented by the following formula: (R1)a(R2)bSiO(4-(a+b))/2(I) (B) a polyorganohydrogensiloxane comprising structural units shown by the following formula: (R3)cHdSiO(4-(c+d))/2(II) and having at least three silicon-bonded hydrogen atoms per molecule, the amount of component (B) being such that the number of silicon-bonded hydrogen atoms in component (B) is from 0.5 to 4.0 per R1 group in the structural units shown by formula (I) of component (A), (C) from 0.1 to 10 parts by weight of a compound selected from the group consisting of an organosilicon compound having, per molecule, at least one silicon-bonded hydrogen atoms and at least one group represented by the following formula: (* CHEMICAL STRUCTURE *) (III) and an acrylic- or methacrylic-functional silane coupling agent, (D) from 0.1 to 10 parts by weight of an epoxyalkylalkoxysilane represented by the following formula: X-Q3-Si(R6)f(OR7)3-f(IV) (E) from 0 to 5 parts by weight of an aluminum chelate compound, and (F) platinum and/or a platinum compound in an amount of from 1 to 100 ppm of the polyorganosiloxane, component (A), in terms of the amount of platinum atoms. All groups and subscripts are identified in the specification.
