This invention relates to a reactive silicone composition for forming a hotmelt material, comprising: (A) an organopolysiloxane resin represented by the specific average unit formula; (B) an organopolysiloxane resin free of alkenyl group and represented by the specific average unit formula; (C) a diorganopolysiloxane represented by the specific average formula; (D) an organohydrogenpolysiloxane having two silicon-bonded hydrogen atoms in a molecule; (E) an organohydrogenpolysiloxane having at least three silicon-bonded hydrogen atoms in a molecule; and (F) a hydrosilylation catalyst. The reactive silicone composition can be reacted to form a hotmelt material having excellent shelf life stability, instant adhesion performance by hotmelt process.
