Abstract

Beschrieben werden neue Zusammensetzungen enthaltend (A) mindestens eine Organosiliciumverbindung aus Einheiten der Formel Ra (R1O) bSiO(4-a-b)/2 (I), wobei R gleich oder verschieden sein kann und ein Wasserstoffatom oder einen einwertigen, ggf. substituierten, SiC-gebundenen aliphatischen Kohlenwasserstoffrest mit 1 bis 30 C-atomen, R1 gleich oder verschieden sein kann und ein Wasserstoffatom oder einen einwertigen, ggf. substituierten Kohlenwasserstoffrest mit 1 bis 4 C-atomen, a 1, 2 oder 3 und b 0 oder 1 bedeutet, mit der Maßgabe, dass die Summe a+b<3 ist, und dass diese Organosiliciumverbindung bei 25°C und 101,425 kPa eine Viskosität von 0,00001 m2/s bis 0,01 m2/s hat. (B) mindestens eine Organosiliciumverbindung aus Einheiten der Formel Rc (R1O) dSiO(4-a-b)/2 (II), wobei R und R1 die oben angegebene Bedeutung haben, c 1, 2 oder 3 und d 0 oder 1 ist, mit der Maßgabe, dass die Summe c+d<3 ist, und dass diese Organosiliciumverbindung bei 25°C und 101,425 kPa eine Viskosität von mindestens 1 m2 / s hat, und (C) mindestens einen Zusatzstoff ausgewählt aus (C1) Füllstoffpartikeln und/oder (C2) Organopolysiloxanharz aus Einheiten der Formel R2 e (R3O) fSiO(4-e-f)/2 (III), worin R2 die Bedeutung von R und R3 die Bedeutung von R1 haben, e 0, 1, 2 oder 3 und f 0, 1, 2 oder 3 ist, mit der Maßgabe, dass die Summe e+f<3 ist und in weniger als 50 % aller Einheiten der Formel (III) im Organopolysiloxanharz die Summe e+f gleich 2 ist.
