Zusammenfassung:	A CURABLE SILICONE COMPOSITION COMPRISING: AN ALKENYL-CONTAINING ORGANOPOLYSILOXANE (A) THAT CONTAINS: A DIALKYLPOLYSILOXANE (A-1) HAVING ON AVERAGE AT LEAST 2 ALKENYL GROUPS IN ONE MOLECULE HAVING A 25°C VISCOSITY IN THE RANGE OF 5,000 TO 35,000 MPA.S, AND A ALKENYL-CONTAINING ORGANOPOLYSILOXANE RESIN (A-2) CONSISTING OF SIO4/2 UNITS, R¹₂R²SiO1/2 UNITS, AND R¹₃SiO1/2 UNITS (WHERE R¹ DESIGNATES ALKYL GROUPS WITH 1 TO 10 CARBON ATOMS, AND R² DESIGNATES ALKENYL GROUPS) WITH THE CONTENT OF ALKENYL GROUPS RANGING FROM 3.5 TO 5.0 MASS %, AND WITH THE RATIO OF THE SUM OF THE MOLE NUMBERS OF THE R¹₂R²SiO1/2 UNITS AND R¹ ₃SiO1/2 UNITS TO 1 MOLE OF THE SiO4/2 UNITS IN THE RANGE FROM 0.5 TO 1.4; AN ORGANOPOLYSILOXANE (B), WHEREIN SILICON-BONDED HYDROGEN ATOMS ARE IN AN AMOUNT OF AT LEAST 0.7 MASS %; AND A HYDROSILYLATION CATALYST (C). THE COMPOSITION IS CAPABLE OF FORMING A FLEX-RESISTANT, HIGHLY TRANSPARENT CURED SILICONE PRODUCT WITH NON-TACKY SURFACE.
