A polysilane composition characterized as containing a polysilane compound and a silicone compound in the ratio (polysilane compound:silicon compound) by weight of 80:20-5:95, and also containing an organic peroxide in the amount of 1-30 parts by weight, based on 100 parts by weight of the polysilane compound and silicone compound, wherein the silicone compound contains 40-100% by weight of a double bond containing silicon compound.

Polysilane composition, optical waveguide and method for fabrication thereof

This invention relates to a method for forming a coating film which comprises applying an epoxy resin powder coating (A) onto a substrate by electrostatic coating, half-baking the resultant uncured coat, applying a polyester resin powder coating (B) onto the half-baked coat by electrostatic coating, and baking the two uncured coats simultaneously, wherein the epoxy resin powder coating (A) and the polyester resin powder coating (B) is such that the gel time ratio [epoxy resin powder coating (A)]/[polyester resin powder coating (B)] at 180.degree. C. is 1/1 through 1/5, the gel time of the epoxy resin powder coating (A) at 180.degree. C. is 40 to 400 seconds, and the gel time of the polyester resin powder coating (B) at 180.degree. C. is not over 500 seconds.
