Does Restek offer custom surface treatments?

30 Jul 2025

For any custom coatings, Restek recommends that the customer deal directly with SilcoTek. Visit www.silcotek.com or call them at 814-353-1778.

On January 1, 2009, the Restek Performance Coatings Division became SilcoTek Corporation, an independent company led by Restek Founder Paul Silvis and members of the Performance Coatings team. The company focuses on developing new coating technologies for the process, analytical, gas, oil and semiconductor markets.

The creation of independent SilcoTek Corporation was part of Restek Corporation’s January 1, 2009 transition to 100 percent employee ownership under an ESOP structure. That move, which had been a part of the company’s corporate planning since its inception in 1985, was designed to ensure Restek’s stability and continued growth while maintaining its status as an independent chromatography consumables manufacturer.

SilcoTek remains a key supplier to Restek, and Restek in turn continues to offer Siltek, Sulfinert, and Silcosteel coated products for chromatography markets.
