Our Goal: Zero Disappointments

At SilcoTek, we base our success on delivering an outstanding Plus 1 customer service experience coupled with exceptional coating quality.  Our goal is to coat your parts perfectly the first time without altering them in any way aside from adding our high performance treatments to the surface.  We call this effort Zero Disappointments, or Zero D, and our entire quality system is based around this basic yet critical principle. 

SilcoTek quality control mechanisms are designed to meet our goal of Zero Disappointments: 


  • Incoming Inspection - Upon arrival to our facility, parts are visually inspected and photographed for traceability.  Technicians search for any damage that may have occurred in transit or that the customer may otherwise be unaware of.  For new parts or questionable substrates, we use a handheld x-ray fluorescence (XRF) analyzer to confirm that the substrate material is compatible. 

    If we find anything out of the ordinary, our customer service group immediately contacts the customer for their disposition on how to proceed (or not proceed) with the coating process.  At this stage, parts with special instructions for fixturing, handling, surface preparation, etc. are given custom traceable routings to ensure proper processing.

  • After Surface Preparation - SilcoTek's surface preparation process is critical to a good coating (learn just how critical in this whitepaper).  From this point forward, all parts are glove-handled to ensure that even fingerprints do not contaminate the surface.

    The surface prep team visually inspects parts to ensure 1) that no incompatible substrates or assemblies were overlooked at receipt and 2) the parts are free of any residue that would negatively impact the coating.

  • After Coating - The most thorough inspection occurs after the CVD coating process.   Once parts have cooled and are removed from the oven, they are moved to the inspection queue.  Quality control technicians perform a thorough visual inspection this time focusing on the output quality of the coating.  The "rainbow" color variation that's common with Silco'd parts represents very slight differences in thickness that reflect light differently.  QC technicians are checking to ensure the parts are free of visual defects, and we meet the process specifications we set with the customer.  This includes paying special attention to critical and machined surfaces, weld joints, tortuous pathways, etc.  

  • Certification - Once parts pass inspection and are packaged, we certify that your product(s) were coated consistent with SilcoTek coating specifications.  SilcoTek's coatings are compliant with other regulatory requirements such as REACH and RoHS32, as well as company-wide management system standards such as ISO 9001.

Making the Grade

SilcoTek's coating process is designed to make customers say "wow" when they see how their newly upgraded parts look and perform.  We involve the customer from the beginning to ensure our process is optimized to meet their expectations.  If it isn't, we work with them to produce the best coating possible for their application.

Coating Certifications & Compliance Statements


ROHS-compliant    REACH-logo.jpg    NSF MARK.gif


SilcoTek's chemical vapor deposition (CVD) coating process is unlike any other, but it is especially unique because of its environmentally friendly nature.  There are two byproducts from this process: water and sand.

Each coating's composition can be found on their data sheets.


SilcoTek Compliance Statements and Coating Certifications

SilcoTek's official RoHS and REACH compliance along with SDS exemption statements are listed below along with coating certifications from relevant internationally-recognized agencies:


Safety Data Sheet (SDS) Exemption

SilcoTek® does not provide SDSs for our coatings as they are not hazardous chemical products. 

SilcoTek’s state-of-the-art CVD processes deposit a thin (0.0005um – 2um) ceramic layer bonded to a customer’s substrate.  The layer is comprised of elemental combinations of silicon, oxygen, and carbon, with no CFCs or other toxic chemicals.
