Beschreibung
Zusammenfassung:	Hotmelt silicone compositions are provided including:(A) a resinous alkenyl group-containing organopolysiloxane component, in which the silicon atom-bonded organic groups do not include an epoxy group-containing organic group, wherein the resinous alkenyl group-containing organopolysiloxane component includes(A-1) a resinous alkenyl group-containing organopolysiloxane including at least two alkenyl groups per molecule and free from a (Ar2SiO2/2) unit, and(A-2) a resinous alkenyl group-containing organopolysiloxane including at least two alkenyl groups per molecule and at least one (Ar2SiO2/2) unit;(B) an organohydrogenpolysiloxane having at least two silicon atom-bonded hydrogen atoms per molecule; and(C) a curing catalyst.The resinous alkenyl group-containing organopolysiloxane (A-1) is included in an amount of about 5 mass % or more based on the total mass of all the organopolysiloxane components in the hotmelt silicone composition.
