SilcoTek coated a diamond like coating (DLC) with our unique hydrophobic and oleophobic coating and compared the moisture and oil stability after high temperature exposure.  The SilcoTek coated surface performed significantly better in contact angle testing.  


New Coating Hydrophobic and Oleophobic


An Unexpected Result

SilcoTek achieved significant improvement in hydrophobicity and oleophobicity compared to the uncoated DLC surface.  More impressively, the new coating remained stable when exposed to high temperatures for and improved dry friction performance after oxidative high temperature exposure in dry N2.  Results are tabulated below.
