Non-Wetting Coating Properties

Prevent Contamination Improve Product Quality 

SilcoTek® Non-Wetting Coatings Prevent Moisture Contamination and Improve Analytical Performance in Laboratory and Process Applications

SilcoTek's inert high temperature barrier coatings enhance hydrophobic interaction between critical flow path surfaces and your product.  Dursan® coating improves moisture repelling properties of stainless steel, glass, and ceramic surfaces by 60% or more, minimizing wetted surface effects.

Coating critical flow path surfaces help process engineers and analysts manage moisture and improve results.  Comparative studies show SilcoTek® coated flow paths adsorb and retain significantly less water than an uncoated stainless steel surface.

Solving Moisture Contamination Problems with Hydrophobic CVD Coatings 

SilcoTek's patented silicon chemical vapor deposition (CVD) coating technology can be applied to complex or narrow part configurations without impacting even extremely tight tolerances.  Comparative studies show SilcoTek non-wetting coatings, like Dursan, dramatically improve water repelling properties when applied to stainless steel, metal alloy, glass, or ceramic surfaces.

Solve common moisture related problems:

  • Contamination
  • Sample loss due to adsorption
  • Test failures 
  • Corrosion
  • Calibration failures

Our low surface energy (high contact angle) surface repels water, preventing system contamination and improving analytical test reliability.  Comparative testing shows the Dursan® coated surfaces significantly improve hydrophobicity by reducing surface energy by 60% or more.  Surface energy water droplet testing below compares various coated surfaces.  Stainless steel, a high surface energy material, exhibits significant wetting and a very low water droplet contact angle (36 degrees, below left), causing moisture control problems.  The Dursan low energy surface shows minimal wetting and a high contact angle, improving hydrophobicity and preventing adsorption, contamination and surface outgassing.
