Abstract

A silicone elastomer cured product having radical reactivity obtained by curing a composition is disclosed. The composition comprises (A) a chain organopolysiloxane having a curing reactive group, and optionally (B) an organohydrogen polysiloxane, (C1) a curing agent, and (D) an organopolysiloxane resin. The surface of the cured product has radical reactivity with, for example, an adhesive, and is easily removable along with, for example, adhesive tape after use as a protective material. In general, the cured product has excellent heat resistance and flexibility and exhibits good adhesion and conformity to a substrate so as not to separate from a substrate even when the cured product is cut together with the substrate while remaining easily removable from the substrate when desired. A protective material for an electronic component made of the cured product is also disclosed.
