Title:
SINGLE-COMPONENT ADDITION-TYPE POLYSILOXANE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2019/129131
Kind Code:
A1
Abstract:
The present invention relates to a single-component addition-type polysiloxane composition which can remain stable over a long period of time at room temperature or low temperature, but can cure rapidly upon heating. The present invention further relates to a process for the preparation of the single-component addition-type polysiloxane composition and to the use of the composition, particularly in the fields of electronics, electricity, communications, automotive, high-speed railway, aerospace, medical and wearable smart devices, and the like. The present invention also relates to the use of a combination of at least one heterocyclic carbene ligand/metal complex catalyst and at least one inhibitor in a single-component addition-type polysiloxane composition; and to a hydrosilylation method including the use of a combination of at least one heterocyclic carbene ligand/metal complex catalyst and at least one inhibitor.
