본 발명은, 황화방지 코팅재료로서, (A)하기 일반식(1)로 표시되는 직쇄상 오가노폴리실록산, JPEGpct00010.jpg51123 (B)1분자 중에 2개 이상의 규소원자결합 수소원자를 갖는 오가노하이드로겐폴리실록산, (C)결정성 실리카 및 탈크로부터 선택되는 1종 이상, (D)1분자 중에 1개 이상의 페닐기를 갖고, 또한, 알케닐기 및 규소원자결합 수소원자를 갖지 않는, 직쇄상의 오가노폴리실록산, (E)백금족 금속을 포함하는 하이드로실릴화 촉매, 및, (F)산화세륨을 포함하고, 또한, 금속가루 및 금속도금가루를 함유하지 않는 것을 특징으로 하는 황화방지 코팅재료이다. 이에 따라, 금속가루 및 금속도금가루를 함유하지 않고, 고온환경에 있어서의 내구성이 우수하며, 또한 내황화성을 갖는 경화물을 부여하는 부가경화형 실리콘 조성물로 이루어지는 황화방지 코팅재료를 제공할 수 있다. The present invention is an anti-sulfuration coating material, including: (A) a linear organopolysiloxane represented by the following general formula (1); (B) an organohydrogenpolysiloxane having two or more hydrogen atoms bonded to silicon atoms within one molecule; (C) one or more substances selected from crystalline silica and talc; (D) a linear organopolysiloxane having one or more phenyl groups within one molecule and having neither an alkenyl group nor a hydrogen atom bonded to a silicon atom; (E) a hydrosilylation catalyst containing platinum group metal; and (F) cerium oxide, wherein the anti-sulfuration coating material is free from metal powder or metal plating powder. This makes it possible to provide an anti-sulfuration coating material made of an addition curing silicone composition, which does not contain metal powder and metal plating powder and is excellent in durability in a high-temperature environment, and can provide a cured material having sulfuration resistance.
