Abstract
(DE)
Vernetzbare Massen auf der Basis von Organopolysiloxanen, dadurch gekennzeichnet, daß sie zusätzlich zu Organopolysiloxanen mindestens eine niedermolekulare Organosiliciumverbindung mit 2 bis 17 Siliciumatomen aus Einheiten der Formel (I) R1aR2b(OR3)cSiO4-(a+b+c)/2 enthalten, wobei R1, R2, R3, a, b und c die in Anspruch 1 angegebene Bedeutung haben, mit der Maßgabe, daß niedermolekulare Organosiliciumverbindungen aus Einheiten der Formel (I) mit b = 0 mindestens eine Einheit der Formel (I), in der a gleich 0 oder 1 ist, und mindestens eine Einheit der Formel (I), in der a gleich 3 ist, aufweisen.
(EN)
The invention relates to crosslinkable materials based on organopolysiloxanes. Said materials are characterised in that in addition to organopolysiloxanes they contain at least one low-molecular organosilicon compound with 2 to 17 silicon atoms comprising units of the formula (I) R1aR2b(OR3)cSiO4-(a+b+c)/2, R1, R2, R3, a, b and c having the meaning given in claim 1 provided that low-molecular organosilicon compounds comprising units of the formula (I) where b is 0 have at least one unit of the formula (I) in which a is 0 or 1, and at least one unit of the formula (I) in which a is 3.
(FR)
L'invention concerne des matières réticulables à base d'organopolysiloxanes. Ces matières sont caractérisées en ce qu'elles contiennent, outre les organopolysiloxanes, au moins un composé organosilicié de faible poids moléculaire avec 2 à 17 atomes de silicium et comportant des unités de la formule (I) R1aR2b(OR3)cSiO4-(a+b+c)/2, R1, R2, R3, a, b et c ayant la notation donnée dans la revendication 1, à condition que les composés organosiliciés de faible poids moléculaire comprenant des unités de la formule (I), où b = 0, présentent au moins une unité de la formule (I) dans laquelle a est égal à 0 ou 1, et au moins une unité de la formule (I) dans laquelle a est égal à 3.
