Abstract:
A varnish composition for producing an electrically insulative thermoset coating is disclosed. The varnish composition includes a functionalized poly(phenylene ether) having at least one aliphatic unsaturated group and exhibiting an intrinsic viscosity in the range of about 0.06 to about 0.25 deciliter per gram, measured in chloroform at 25° C. The varnish composition further includes an unsaturated polyester resin or vinyl ester resin, a reactive liquid monomer, and a compatibilizing agent. When cured, the polymers and reactive liquid monomer form an electrically insulative thermoset.
