Title:
金属触媒の存在下で脱水素縮合により架橋可能なシリコーン組成物
Document Type and Number:
Japanese Patent JP2006500432
Kind Code:
A
Abstract:
The invention relates to a silicone composition =SiH/=SiOH which can be polymerized/cross-linked by dehydrogenization with condensation in the presence of a catalyst which is suitably selected in order to complete one of the specifications announced hereafter: kinetics, concentration/efficiency ratio of the catalyst, cost, reduction of the catalyst activation temperature (room temperature), control of the gaseous hydrogen discharge and the quality of the polymerized product and the cross-linked network, in addition to limitation of secondary reactions. Said composition comprises: A) at least one POS =SiH; B) at least one POS =SiOH; C) at least one metallic catalyst selected from the group of organometallic complexes comprising at least one of the following metals: Ir, Ru, Mn.; D) optionally one cross-linking inhibiting agent; E) optionally at least one POS resin; F) optionally at least one charge. The invention also relates to the catalyst C and methods involving the cross-linking of silicon by dehydrogenization with condensation (anti-cling coating on paper).
