Self-adhering silicone rubber with low compression set

A liquid silicone composition curable to a rubber, the composition comprising:

• an alkenyl-containing polydiorganosiloxane having an average ratio of organo radicals per silicon atom within a range greater than 2 up to and including 2.03, and each organo radical of the polydiorganosiloxane being a monovalent radical selected from the group consisting of hydrocarbon radicals and fluorinated alkyl radicals both having less than 7 carbon atoms per radical,
• an organohydrogensiloxane having an average of at least 3 silicon-bonded hydrogen atoms per molecule and valences of any silicon atom in the organohydrogensiloxane not satisfied by a hydrogen atom is satisfied by a divalent oxygen atom or an organo radical wherein each organo radical is a monovalent radical selected from the group consisting of hydrocarbon radicals and fluorinated alkyl radicals both having less than 7 carbon atoms per radical, the organohydrogensiloxane having no more than one silicon-bonded hydrogen atom on any one silicon atom, the amount of organohydrogensiloxane providing a ratio of silicon-bonded hydrogen atoms to alkenyl groups from the polydiorganosiloxane of 1.2 to 1.9,
• a hydrosilation catalyst containing a metal of the platinum-group,
• an aluminum chelate in an amount to provide 0.05 to 20 ppm aluminum based on the polydiorganosiloxane, and
• 0.05 to 0.40 parts epoxytrialkoxysilane per 100 parts polydiorganosiloxane where the alkoxy radicals of the epoxytrialkoxysilane have 1 to 4 carbon atoms.
