ElectroBond® – Electrosurgical Blade

Download Tech Sheet

ElectroBond® is a specifically formulated coating for high-temperature nonstick applications. It allows
electrosurgical cutting devices to work more efficiently and consistently. ElectroBond® is an extremely durable, black, smooth, low-friction coating that permanently bonds to metal surfaces including 300 and 400 series stainless steel.

The raw materials and resin systems are listed in the Code of Federal Regulations, Title 21, Food and Drugs, Parts 175 and 177 for materials suitable for food contact.

Optimizing Non-Stick Electrosurgical Device Performance

In the past, the PTFE coating on endoscopic electrosurgical blades was not effective in preventing the buildup of eschar (burnt tissue) during surgical procedures, resulting in blades roughened by the adherence of tissue. Manufacturers needed a non-PTFE coating for their stainless electrosurgical blades.

In response to this problem, the SSG team has developed a durable high-temperature release coating material. ElectroBond® was tested and succeeded in providing a smooth non-stick pore-free surface. Unlike the PTFE surface of standard electrosurgical blades and devices (ball, wire, needle, etc.), ElectroBond® resists damage and scratching.

The SSG team has completed all of the 510K certification documentation required for ElectroBond® to receive FDA approval for these electrosurgical device blades and manufacturers now have internationally qualified ElectroBond® electrosurgical coated blades that overcome the performance problems inherent in PTFE coatings.
