SSG Develops ElectroBond Solving PTFE Performance Problems for Electrosurgical Device Manufacturer

The PTFE1 coating on endoscopic electrosurgical blades was not effective in preventing the buildup of eschar (burnt tissue) during surgical procedures, thus resulting in blades roughened by the adherence of tissue.  The manufacturer of these devices needed a non-PTFE coating for their stainless electrosurgical blades. 


On a micro level SSG determined that there were miniature voids in the PTFE coating which had become attachment sites for the eschar. Initially, a topcoat of PTFE was tried in hopes that it would eliminate the buildup. Testing determined that the additional layer did delay the buildup, but did not prevent it completely.  PTFE, being relatively soft, scratched easily once a surgeon interrupted the procedure to wipe the blade on a “scratch pad” to remove the adhered eschar.

The SSG team developed a durable high-temperature release coating material. Electro Bond 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), Electro Bond resisted damage and scratching. Being 8 times more abrasion-resistant than PTFE in milligram weight loss tests, it successfully passed the scratch pad test.

PTFE Coating with High Abrasion Resistance with ElectroBond from Surface Solutions

The SSG team completed all the 510K certification documentation required for Electro Bond to receive FDA approval for these electrosurgical device blades and the manufacturer now has an internationally qualified Electro Bond electrosurgical blade that overcomes the performance problems inherent in PTFE coatings.
