Insulating varnish and insulated electrical wire using same

摘要: An insulating varnish forms an coating film having a shape that corresponds to the of opening die, uniform thickness. The is applied onto surface conductor, subsequently passes through die remove excess varnish, and then dried or baked form on conductor. has viscosity 10 Pa·s more measured by B-type viscometer at 30° C. preferably contains no filler, polyimide precursor solution. Since high viscosity, baking solidification can be performed while maintaining formed when die.
