Cautery Tips

PTFE Coatings To Reduce Eschar And Buildup

Non-Stick/Easy-Clean Coated Cautery Tips

Our medical coating systems are infused and fortified with PTFE to greatly reduce tissue sticking or buildup on cautery tips known as “eschar”.  Eschar buildup is the most common issue associated with the intraoperative use of electrocautery and can be problematic for the end user. This buildup will also directly affect the dispersion of electrical energy and prevent proper sealing of small and large vessels and also promotes longer surgical time. This is where utilizing our  850G-9004 coating can greatly reduce the coefficient of friction and assist with easy clean ability, minimizing any sticking or charring on the electrode.

Coating Uses

  • Electrosurgical Devices
  • Hospital and Lab Equipment
  • Dental Equipment
  • Surgical Instruments
  • Ask our team if your device or component can be coated!

Coating Equipment & Application Recommendations

All of our PTFE coatings can be applied via spray, dip or spool-to-spool methods. Proper pre-coating wire cleaning treatment and post-application curing equipment is critical to guarantee performance and durability. Acceptable curing equipment includes high-temperature ovens which can safely maintain temperatures of 246 °C  (475 °F) or utilize IR ovens. This will ensure proper sintering of the coatings onto the wire and promote the best surface characteristics that can be achieved.

ASTM & ISO Standards Met

 

  • ASTM 1894 Coefficient of Friction
  • ASTM D3359 Adhesion Test
  • ISO 7802 Wire Wrap Test
  • ISO 11070 Corrosion Resistance Test
  • Coated smooth stainless steel panels passed Adhesion test, ASTM-3359
  • Coated stainless steel catheter guidewires passed flexibility/adhesion tests, ISO 7802 Annex F wrapping test
  • Coated stainless steel catheter guidewires passed corrosion resistance, ISO11070 Annex B, saline soak test

All Miller-Stephenson’s formulations generate very uniform thin films which exceed all ISO and ASTM requirements.
