About SilcoTek®

SilcoTek Makes Your Product or Process Perform Better

SilcoTek® is the world's leading provider of high performance coatings applied by chemical vapor deposition, or CVD. We became a coatings company because we have a passion for helping people and businesses conquer their most difficult challenges. 


By improving the surface properties of the materials they use, our customers can run their machines longer, manufacture complex products more efficiently, and continue to develop innovations that push the scientific and industrial world forward. We don't sell any products because we're solely focused on offering coatings that make your product better. Watch our process video and see how SilcoTek can improve your products.

Plus 1 means that every SilcoTek employee strives to exceed your expectations, whether you're asking technical questions, placing an order, or troubleshooting. Equally important, we maintain a workplace culture where our employees enjoy coming to work as much as they enjoy going home at the end of the day.
