Title
(DE) DURCH HYDROSILYLIERUNGSREAKTION VERNETZBARE MASSEN
(EN) COMPOUNDS THAT CAN BE CROSSLINKED BY WAY OF HYDROSILYLATION REACTION
(FR) MASSES RÉTICULABLES PAR RÉACTION D’HYDROSILYLATION
Abstract
(DE)
Die vorliegende Erfindung betrifft durch Hydrosilylierungsreaktion vernetzbare Massen, insbesondere solche, die durch ultraviolette und/oder sichtbare Strahlung aktivierbare Platinkatalysatoren enthalten, wobei der Gehalt starker Säuren (S) mit einem pKs-Wert < 2,5 kleiner 0,3 Gew.-ppm ist, deren Herstellung, ihre Verwendung sowie daraus hergestellte Vernetzungsprodukte, wie durch Bestrahlung hergestellte Siliconelastomere.
(EN)
The invention relates to compounds that can be crosslinked by way of a hydrosilylation reaction, in particular compounds containing platinum catalysts that can be activated by UV and/or visible radiation, the content of strong acids (S) with a pKs value < 2.5 being less than 0.3 weight ppm. The invention also relates to the production thereof, to their use and to crosslinked products produced therefrom, such as silicone elastomers produced by radiation.
(FR)
La présente invention concerne des masses réticulables par réaction d'hydrosilylation, en particulier ceux qui contiennent des catalyseurs au platine activables par le rayonnement ultraviolet et/ou visible. La teneur en acides forts (S) avec une valeur pKs < 2,5 est inférieure à 0,3 ppm en poids. L'invention concerne également la fabrication desdites masses réticulables, leur utilisation et des produits de réticulation fabriqués à partir de celles-ci, tels que des élastomères de silicone fabriqués par irradiation.
