RF-NonStick Coating

A ceramic non-stick surface technology developed to address the limitations of polymer-based coatings for electrosurgery

Conventional non-stick coatings used on electrosurgical electrodes are often polymer-based and can degrade under the elevated temperatures associated with RF cutting and coagulation. RF NonStick Coating is a ceramic surface treatment developed to reduce tissue adhesion and maintain surface stability under RF operating conditions, without reliance on PTFE or related materials.

Design Intent and Material Characteristics

Non-stick surface treatments are used in electrosurgical devices to reduce tissue adhesion, limit eschar accumulation, and support consistent RF energy transfer. RF NonStick Coating is implemented as an all-ceramic surface treatment selected for thermal stability and mechanical durability under RF operating conditions.

Ceramic coatings differ from polymer-based approaches in their resistance to high-temperature degradation, surface wear, and repeated sterilization cycles commonly encountered in electrosurgical use.

Durability and Sterilization Considerations

RF NonStick Coating is designed to tolerate repeated device use and common sterilization methods, including steam autoclaving. The ceramic surface provides resistance to scratching, peeling, and delamination that can occur with softer coating materials when exposed to repeated heating and handling.

Biocompatibility and Procedural Environment

RF NonStick Coating does not contain PTFE or related fluoropolymer materials. Avoiding PTFE reduces the potential for degradation byproducts associated with high-temperature polymer coatings and supports a safer procedural environment for both patients and clinical staff.

Functional Impact on Electrosurgical Performance

By reducing tissue adhesion at the active electrode surface, RF NonStick Coating supports more consistent RF energy delivery during cutting and coagulation. Reduced tissue sticking can help limit interruptions related to electrode cleaning and contribute to more predictable tissue interaction.

Application Across RF Kinetics Devices

RF NonStick Coating is applied across select RF Kinetics electrosurgical devices where controlled tissue interaction and surface stability are important to device performance.

Technology Development and Implementation

RF NonStick Coating is developed and implemented as part of RF Kinetics’ broader work in materials selection, surface treatment, and RF device manufacturing.
