Title:

ORGANOPOLYSILOXANE COMPOSITION FOR TRANSDUCER, LAMINATE COMPRISING CURED FILM THEREOF, USE THEREFOR, AND MANUCATURING METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2023/282270

Kind Code:

A1

Abstract:

The purpose of the present invention is to provide a laminate obtained by stacking an organopolysiloxane cured film that is a dielectric layer and an electrode layer/substrate layer, wherein the adhesion of an interface of the cured film is improved, and problems such as peeling and defects caused by insufficient adhesive strength and conformability of the film are unlikely to occur. The purpose of the present invention is also to provide a use and a manufacturing method therefor. A curable organopolysiloxane composition for a transducer according to the present invention contains (A) a polysiloxane having a C=C curing reactive group, (B1) an organohydrogen polysiloxane with a side-chain SiH, (B2) an organohydrogen polysiloxane with a terminal SiH, (C) a catalyst for a hydrosilylation reaction, (D) a reinforcing filler, and (E) an adhesiveness-imparting agent. Regarding the number of of Si-H atoms in components (B1) and (B2) and the total number (Vi) of the curing reactive group in component (A), the value of px1={HB1/HB2}/{(HB1+HB2)/Vi} is in the range from 0.1-6.0.
