PURPOSE:To form the clad layer having a high strength by comprising a fluoropolysiloxane contg. a vinyl group as a main component, and by forming a hardener from a specific hydrogen contg. fluoronated silicone compd. CONSTITUTION:The titled composition comprises the fluoropolysiloxane contg. the vinyl group as the main component. The hardener is composed of the hydrogen contg. fluoronated silicone compd. The perfluoropolysiloxane contg. the vinyl group contained as the main component is preferable to be 0.5-5mol% the vinyl group contg. siloxane unit in the fluoropolysiloxane. The viscosity of the hydrogen contg. silicone compd. of the hardener is preferable to be <=1,000cps. The fluorine content of the hydrogen contg. fluoronated silicone compd. is >=30wt%. If the content of the main component is within the prescribed range, it makes very easy to mix the main component and the hardener uniformly. |
