Unique Surgical Devices

PTFE Coating's For Todays Surgical Devices

Coating Unique Surgical Devices and Substrates

With minimally invasive surgical procedures on the rise, there is a demand for unique surgical devices to be smaller, stronger and capable of executing multiple job functions all in one. Miller-Stephenson’s medical coatings are designed to cover and coat extremely tough geometrical device configurations, as well as unique alloy substrates without delamination or coating buildup. These applications are routinely combined with unique alloy substrates, that require a low-bake temperature PTFE coating like Miller-Stephenson’s  850G-1000.850G-1000

What Type of Items Can Be Coated?

  • Robotic Components
  • Nitinol Components
  • Hospital and Lab Equipment
  • Dental Equipment
  • Vascular Wires/Urological Wires
  • Surgical Instruments
  • Trocars
  • 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.
