Abstract
(EN)
The present disclosure provides methods of making organosiloxane polymer compositions from hydrosilylation curable compositions comprising at least the components (a) and (b) and at least one of components (c) and (d): (a) an organosiloxane resin material comprising aliphatic unsaturation; and (b) an organosiloxane crosslinker comprising multiple silicon atom-bonded hydrogen atoms (e.g., an "SiH siloxane"); in combination with at least one of (c) at least one organosiloxane comprising at least two silicon atom-bonded hydrogen atoms; and (d) at least one organosiloxane comprising at least two silicon atom-bonded hydrocarbyl groups comprising aliphatic unsaturation (e.g., a "di-vinyl functional siloxane"). Such hydrosilylation curable compositions have, in some instances, significantly faster cure speed, relative to their condensation curable counterparts. A faster cure speed can be important for encapsulating electronic devices, such as light-emitting diode (LED) chip devices, including devices having tall structures.

La présente invention concerne des procédés de préparation de compositions polymères d'organosiloxane à partir de compositions durcissables par hydrosilylation comprenant au moins les constituants (a) et (b) et au moins un des constituants (c) et (d) : (a) un matériau de résine d'organosiloxane comprenant une insaturation aliphatique ; et (b) un agent de réticulation d'organosiloxane comprenant de multiples atomes d'hydrogène liés à un atome de silicium (par exemple, un "siloxane SiH ") ; en combinaison avec au moins l'un parmi (c) au moins un organosiloxane comprenant au moins deux atomes d'hydrogène liés à un atome de silicium ; et (d) au moins un organosiloxane comprenant au moins deux groupes hydrocarbyle liés à un atome de silicium comprenant une insaturation aliphatique (par exemple, "siloxane à fonctionnalité divinyle"). Ces compositions durcissables par hydrosilylation présentent, dans certains cas, une vitesse de durcissement considérablement plus élevée par rapport à leurs équivalents durcissables par condensation. Une vitesse de durcissement plus élevée peut être importante pour l'encapsulation de dispositifs électroniques, tels que des dispositifs à puce de diodes électroluminescentes (DEL), y compris des dispositifs présentant des structures de grande taille.
