Coating Data Sheet

The SilcoNert® 2000 coating process results in a chemically protective barrier of amorphous silicon that is further functionalized to provide the most inert surface available (patent info at www.silcotek.com/IP). Applied via chemical vapor deposition (CVD), the SilcoNert®

2000 process is ideal when trace-level testing accuracy ( < parts-per-million) of sulfurs, mercury, ammonia, or other active compounds is imperative.

• Non line-of-sight process; all holes and complex geometries will be coated

• Eliminate adsorption and retesting• Obtain faster calibrations• Gain full confi dence in your analytical results

CHEMICALLY COMPATIBLE The functionalized silicon structure deposited by SilcoNert 2000® provides a highly inert barrier to analytes of interest.

NON-WETTING SilcoNert 2000® doubles the hydrophobicity of stainless steel and is commonly specifi ed in moisture analyzer applications.

INERT TO AMMONIA Inertness enabled by SilcoNert 2000® permits 12x faster response than when using electropolished stainless steel.

HIGH-TEMPERATURE STABLE Coatings produced by SilcoNert 2000® are robust and inert for use up to 450°C, far exceeding the limits of PTFE.
