ADDITION-CURABLE SILICONE RUBBER COMPOSITION AND CURED PRODUCT

摘要

Provided is an addition-curable silicone rubber composition containing (A) an alkenyl group-containing organopolysiloxane having alkenyl groups bonded to at least two silicon atoms per molecule, (B) an organohydrogenpolysiloxane containing hydrogen atoms bonded to at least two silicon atoms per molecule, (C) a platinum catalyst, and (D) a benzotriazole derivative represented by general formula (I) (in the formula, R1 is a hydrogen atom or monovalent hydrocarbon group, R2 is a monovalent organic group) that makes it possible to provide silicone rubber that can lower the compression set without harming the curing rate and suppress discoloration after a heat resistance test.
