What Is SilcoNert?

SilcoNert® is a flexible silicon coating that makes flowpaths inert for better process control, consistent sampling and analytical results.  The patented chemical vapor deposition (CVD) process bonds the coating to stainless steel, alloy, ceramic, and glass, making a high tolerance durable coating even under extreme temperatures and pressures. 



  • SilcoNert® 2000 (Siltek®/Sulfinert®): The ultimate inert silicon coating.  Ideal surface for sampling & transfer in analytical, stack, process, oil & gas applications.   Most inert surface for critical flowpaths. 
  • SilcoNert® 1000 (Silcosteel®): A general purpose barrier coating that prevents contamination, catalysis, and out-gassing.  Ideal for high purity and extreme temperature applications.

An inert flowpath will eliminate surface adsorption and reactivity, improving analytical and process reliability.  Our  coating will stop surface adsorption of active compounds like sulfurs, H2S, ammoniaVOC's, and mercury on stainless steel, alloys, glass, ceramic and carbon surfaces.

Unsurpassed Inertness

Active compounds can be lost in the sample pathway before they can be tested; impacting process control and voiding analytical results.  The chart above shows that after just a few hours of exposure to uncoated stainless steel, reactive H2S and other active compounds are completely lost.  The coated sample cylinders are able to retain the sample for 7 days or more, taking the guesswork out of sampling.  (Data credit: Restek® Corporation).

  • Fast calibration

  • No adsorption

  • No retesting

  • Improve efficiency
