Abstract
A silicone emulsion composition is provided comprising organopolysiloxane, organohydrogenpolysiloxane, surfactant, and water. Two organopolysiloxanes of different type are blended, whereby a cured silicone coating is improved to be fully adherent to plastic film and lightly peelable from pressure-sensitive adhesive. By limiting the SiH content of organohydrogenpolysiloxane, the composition is improved in shelf stability. A specific surfactant is used to control the size of emulsion particles so as to improve wettability to plastic film.
