SilcoTek coatings can improve efficiency and prevent damage to molds or extruders, while solving common material problems like corrosion and mold release. Outgassing, moisture acidity, and abrasive wear take their toll on mold quality and result in costly replacement or repair. SilcoTek® coatings, like Dursan®, reduce friction and stiction while improving moisture and corrosion resistance. SilcoTek coatings bond to process surfaces and act as a non stick, hydrophobic barrier that improves surface performance.
Get our latest extrusion and mold release coating data and learn how to improve productivity, quality, and corrosion resistance. Watch our webinar.
Even under extreme pressure and temperature, SilcoTek® coatings significantly improve mold release and corrosion resistance , allowing more efficient and easy release of product from molds and extending the life of extruders and dies.

Companies turn to SilcoTek® for coating solutions to their most demanding material challenges. They stay with SilcoTek because our team is dedicated to improving your products and processes. Our case studies tell the story of how customers in a wide range of industries have benefited from doing business with SilcoTek.
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 coatings outperform most materials commonly used in mold and extrusion applications.

Our low surface energy (high contact angle) surface combined with a low coefficient of friction improve mold flow and release. Comparative testing shows the Dursan® coated surfaces significantly improve hydrophobicity by reducing surface energy by up to 8x. 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), causing sticking and mold release problems. The Dursan low energy surface shows minimal wetting and a high contact angle of 143 degrees, promoting better mold release.
Comparative pin-on-disk wear and friction testing shows the Dursan® coated surface improves lubricity by 36% over uncoated stainless steel while reducing wear by over 50%.
