Silco'd Coating Technologies

SilcoTek's CVD coatings are uniquely tailored for high performance in specific applications, but their properties can be useful in a variety of others.  

Our patented coating technologies are listed below.  To learn more about SilcoTek's intellectual property, please visit



What's this coating used for?

A tough, corrosion resistant, inert, hydrophobic coating.  Ideal for oil and gas, chemical processing, refining, and other demanding environments.  Also offers very low surface energy for easy cleaning and non-stick properties.

  • Dursan: Improves wear chemical inertness and corrosion resistance of stainless steel while significantly improving surface moisture resistance (hydrophobicity).



What's this coating used for?

The most inert coating available.  

  • SilcoNert 1000 (formerly Silcosteel): A general passivation coating for steel and stainless steel.
  • SilcoNert 2000 (formerly Siltek/Sulfinert): A required coating when analyzing low levels of active, reactive, and organo-sulfur compounds.
    • H2S
    • Mercury
    • NOx
    • VOC's
    • Ammonia
    • Environmental sampling


What's this coating used for?

A corrosion resistant coating that increases the lifetime of system components.

  • Silcolloy (formerly Silcosteel-CR) improves corrosion resistance of stainless steel by an order of magnitude in chlorides & acidic environments.

SilcoKlean Coating

What's this coating used for?

A non-stick coating designed to reduce the onset of carbon coking and fouling on stainless steel.

  • SilcoKlean (formerly Silcosteel-AC) reduces carbon coking or fouling by up to 8x on stainless steel.


What's this coating used for?

A low outgassing, rapid pump down, high purity coating designed to improve ultra high vacuum system performance.

  • SilcoGuard (formerly Silcosteel-UHV) reduces outgassing by 14x and significantly improves vacuum pump down in semiconductor and research systems.
