Zusammenfassung:	A solventless releaser composition is provided comprising (A) an organopolysiloxane containing at least two alkenyl groups and at least one monovalent fluorinated substituent group and having a fluorine content of 30-50 wt% and a viscosity of 100-2,000 mPa-s at 25°C, (B) an organohydrogenpolysiloxane containing at least three SiH groups, (C) a reaction regulator, and (D) a platinum catalyst. The composition is coated and cured to a substrate to form a release liner for use with silicone pressure-sensitive adhesives.
