The silicone resin to be used can be used irrespective of the type such as one-pack type, two-pack type, addition type, condensation type, room temperature curing, and heat curing, as long as it has a viscosity capable of obtaining an appropriate film thickness. . The optimum viscosity varies depending on the target thickness of the silicone resin coating, but is 1 mPa · s to 10,000 mPa · s.
Uncured silicone of 0 mPa · s (25 ° C.) can be used. When the viscosity is less than 1 mPa · s, the viscosity is too low to allow the silicone resin to sufficiently adhere to the heat-resistant film.
If it exceeds 000 mPa · s, the fluidity is poor and it is difficult to coat a stable surface. If necessary, a filler such as finely divided silica, diatomaceous earth, or a highly thermally conductive inorganic filler may be added.

If the thickness exceeds 1.0 mm, it becomes difficult to coat the film by the dipping method, and it is difficult to reduce the size and increase the cost in a fuel cell, particularly in a separator for a polymer electrolyte fuel cell. The position where the silicone resin layer is provided differs depending on the application and the like, and an unnecessary portion can be appropriately masked as needed.
