FIELD: chemistry.
SUBSTANCE: invention relates to a curable composition which forms an organosilicon gel containing at least one (A) organopolysiloxane containing at least two alkenyl groups per molecular which are bonded through a silicon atom, and having viscosity from approximately 10 to approximately 1000000 cP at 25°C. (B) at least one organohydrogenpolysiloxane containing at least two hydrogen atoms per molecule which are bonded through a silicon atom, where said organohydrogenpolysiloxane (B) is used in such an amount that molar ratio of total number of hydrogen atoms bonded through a silicon atom contained in the organohydrogenpolysiloxane (B) to one alkenyl group bonded through a silicon atom contained in the organopolysiloxane (A) ranges from approximately 0.20 to approximately 0.79, (C) filler in amount ranging from approximately 25 to approximately 100 parts per hundred parts of organopolysiloxane (A), (D) a catalyst and (E) an inhibitor, where the restoration time of said curable composition which forms a hysteretic organosilicon gel which is longer than approximately 3 seconds. The invention also relates to a hand held device which has an outer surface, at least part of which contains a hysteretic organosilicon gel. The hand held device is a writing device, a shaver, a toothbrush, a utensil, sports equipment, an instrument, a motor-driven device or steering wheel.
EFFECT: obtaining an organosilicon gel with improved hysteresis.
