SilcoTek

What SilcoTek does

SilcoTek Corporation is a privately held specialty coatings provider founded in 1987 in Bellefonte, Pennsylvania, that applies proprietary chemical vapor deposition (CVD) processes to deposit ultra-thin silicon-based coatings on metal, glass, and ceramic substrates. The company operates from an 80,000 square foot ISO 9001:2015 certified facility and holds over 200 patents across its coating portfolio. Its six core coating families — SilcoNert, Silcolloy, Siltride, Dursan, Dursox, and Notak — span silicon, silicon oxynitride, silicon oxide, and specialty surface chemistries and are engineered to deliver chemical inertness, corrosion resistance, hydrophobicity, or anti-fouling depending on application. The non-line-of-sight CVD process uses gases at approximately 400°C to produce sub-3μm, most under 1.5μm, molecularly bonded coatings that conform fully to complex geometries including sub-micron openings, sharp edges, and tortuous flow paths.

SilcoTek serves industrial and enterprise customers across four primary verticals: semiconductor manufacturing, analytical chemistry and instrumentation, life sciences, and energy. End products supported include gas chromatography and HPLC instruments, semiconductor gas delivery and exhaust abatement systems, medical diagnostic analyzers, oil and gas sampling equipment, and food contact surfaces. Named enterprise customers appearing in case studies include Samsung Austin Semiconductor, Abbott, Armstrong International, Equinor (via Wood), Tacmina, Smith Analytical, Process Insights, and Sensor Sampling Systems (SOR Controls Group). Regulatory certifications on the portfolio — NSF International, FDA 21 CFR 175.300, USP Class VI, ISO 10993 biocompatibility, and SEMI F19 ultra-high-purity compliance — qualify Dursan and other coatings for medical, food contact, and ultra-high-purity semiconductor applications.

The company earns revenue primarily through quote-based CVD coating services in which customers ship parts to its Pennsylvania facility for coating and return. It augments this direct service revenue with value-added offerings including ISO 6 Class 1000 cleanroom packaging, ASTM A967 citric acid passivation, surface preparation, ultrasonic cleaning, and in-house materials analysis. Distribution also flows through a channel partner network that stocks and resells pre-coated products, reducing buyer supply chain friction. A tiered expedite and priority program charges a premium for 3-4 business day or 5+ business day lead-time improvements, addressing time-sensitive semiconductor and analytical chemistry demand where downtime is costly.

Revenue model

1. CVD Coating Services: SilcoTek provides chemical vapor deposition coating services applied to customer parts. Customers send components to SilcoTek's Pennsylvania facility for coating. Pricing is quote-based, determined by part complexity, size, coating type, and volume. The company also offers an expedite program with tiered pricing for faster turnaround.
2. Value-Added Services: Supplemental services including citric acid passivation, cleanroom packaging, precision cleaning, surface preparation, nitric acid stripping, vapor stripping, ultrasonic cleaning, tubing cutting, logistics support, and materials analysis. These services are bundled with coating orders or sold separately to reduce customer supply chain complexity.
3. Channel Partner Product Sales: SilcoTek works with channel partners who stock and sell pre-coated products. Partners apply SilcoTek coatings to their product lines, which are then sold to end customers. This model extends market reach without SilcoTek managing direct product fulfillment.

Core offering

SilcoTek manufactures and applies proprietary chemical vapor deposition (CVD) coatings to metal and ceramic components used in analytical, process, and research instrumentation. The company sells coated parts under multiple branded coating lines (e.g., SilcoNert, Silcolloy, Siltride, Dursan, Dursox, Notak 2000) to industrial customers seeking improved chemical inertness, corrosion resistance, and analytical accuracy. Beyond finished coated parts, SilcoTek also offers CVD coating services for customer-supplied components.

Product overview

SilcoTek is a provider of chemical vapor deposition (CVD) coating services offering over 20 custom coatings for challenging flow path problems. The company provides a portfolio of six core coating products organized into families: Silicon Family (SilcoNert®, Silcolloy®), Silicon Oxynitride Family (Siltride®), Silicon Oxide Family (Dursan®, Dursox®), and Specialty Surface Family (Notak®). These coatings are applied using SilcoTek's proprietary non-line-of-sight CVD technology that creates ultra-thin, molecularly bonded protective layers on metal, glass, and ceramic substrates. The company also offers complementary value-added services including ISO 6 Class 1000 cleanroom packaging, citric acid passivation, surface preparation, metal working, logistics support, and in-house materials analysis capabilities. All coatings are performed from SilcoTek's 80,000 square foot ISO 9001:2015 certified facility in Pennsylvania, USA.
