Abstract
An exceptionally durable insulating coating for surgical instruments and other implements is provided. The coating is a ceramic and polyurethane composite, and exhibits excellent insulative properties in the 500 KHZ to 1 MHZ frequency range. The ceramic coating can be readily applied by plasma deposition techniques. A polyurethane over coating is applied over the ceramic coating and is obtained using a polyester-based aliphatic polyurethane composition.
