Abstract
An electrosurgical device coated an epoxy modified rigid silicone powder coating which includes a solvent-free hydroxyl functional solid phenyl silicone resin in the range of about 40% to about 60% parts per weight of the coating; a calcium metasilicate in the range of about 20% to about 40% parts per weight of the coating; an epoxy cresol novalac resin in the range of about 5% to about 15% parts per weight of the coating; an ultra-fine air micronized muscovite mica in the range of about 0% to about 10% parts per weight of the coating; a 60% active powder version of a methyl alkyl polysilaxane in the range of about 3% to about 7% parts per weight of the coating; a high temperature calcination of coprecipitated compound with manganese-copper-iron in the range of about 0% to about 10% parts per weight of the coating; an o-cresol novolac resin in the range of about 0.5% to about 3% parts per weight of the coating; and an acrylate copolymer in the range of about 0.5% to about 3% parts per weight of the coating. This coating is applied to the surfaces of an electrosurgical device minimize the build-up of charred tissue (i.e., eschar) on the surfaces of the electrosurgical device.
