Title:
CURED SILICONE ELASTOMER HAVING RADICAL REACTIVITY AND USE OF SAME
Document Type and Number:
WIPO Patent Application WO/2019/049950
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to provide: a cured silicone elastomer which has excellent heat resistance, flexibility and the like, and which exhibits good adhesion and followability to a base material and is therefore not separated from the base material even if the cured silicone elastomer is cut together with the base material, while being able to be easily removed from the base material when desired; a protective material for electronic components, which is formed from this cured silicone elastomer; and a use of this cured silicone elastomer. [Solution] A cured silicone elastomer which is obtained by curing a composition that contains (A) a chain organopolysiloxane having a curing reactive group, while optionally containing (B) an organohydrogen polysiloxane, (C1) a curing agent and (D) an organopolysiloxane resin, and which has radical reactivity; and a use of this cured silicone elastomer. The surface of this cured silicone elastomer is radically reactive with an adhesive and the like; and this cured silicone elastomer is able to be easily removed together with an adhesive tape and the like after use as a protective material.
