Our newest coating! A durable, inert, corrosion resistant coating that is harder than steel and highly resistant to acid and base attack. Ideal for valves and components that require a tough scratch resistant coating. Dursan is a hydrophobic surface that strongly repels water.
The ultimate in inert coating technology. Eliminate surface interaction in process, analytical, oil and gas sampling. Allow for fast accurate sampling the first time, every time. Improves test efficiency while reducing overall sampling/analytical cost.
A corrosion resistant coating that increases the lifetime of system components. Improve the corrosion performance of stainless steel, eliminate the use of costly high performance alloys while reducing component corrosion.
A non-stick coating designed to reduce the onset of carbon coking and fouling on stainless steel. Extend maintenance cycles in refining and petrochemical operations, improve engine and fuel delivery performance by reducing carbon build-up on fuel injectors and combustion surfaces.
A low outgassing, rapid pump down, high purity coating designed to improve ultra high vacuum system performance. Reduce vacuum pump-down cycle time, improve product yield by eliminating surface impurities.

Company Profile

During the transition to a 100% employee owned company, Restek’s Performance Coatings or “RPC” division became an independent company led by Restek’s founder Paul Silvis and members of the Performance Coatings team. The new company, called SilcoTek™, will focus on developing new treatment technologies for the passivation, anticoking, automotive, corrosion, and ultra-high vacuum markets. The new organization will remain a key supplier to Restek and Restek will continue to offer Siltek®, Sulfinert®, and Silcosteel® treated products for chromatography markets.

In 1987, Silcosteel® was invented to serve as an alternative means of making fused silica capillary columns. The technology was further refined from 1987 to 2008 with several patents obtained to protect its unique properties. Restek’s MXT capillary columns, Siltek® inlet liners, injection ports, and many other chromatography products utilize Silcosteel® Chemical Vapor Deposition (CVD) technology. The first non-chromatography application was in portable bomb sniffers and instruments designed to detect low levels of explosives in airports and public spaces. Since then the technology has found its way into refining and petrochemical plants, industrial fittings and valves, analytical instrument flow paths, aerospace, and the automotive industry.

As Restek grew, it became apparent that this technology had to be separated into its own business to reach its full potential. Restek is a market driven business that focuses on creating products for the chromatography market. SilcoTek™ is a technology driven business that focuses on finding new and unique applications for our surface enhancing technologies. Channel conflicts, internal resource conflicts, and customer perceptions that Restek either competed or was only doing CVD coatings as a sideline business hampered the growth of this product line.

Separating SilcoTek™ into a new business will allow the team to focus on innovative treatment solutions for our chromatography customers and will allow us to offer previously unavailable technologies to new markets with material limitations.

The analytical market will remain a key component of SilcoTek’s business. If you have custom parts to treat, please contact SilcoTek™ at 814-353-1778 or go online to SilcoTek.com for more information. You will find the same Plus One customer service at SilcoTek™ that Restek is famous for!
