Getting parts coated shouldn't be complicated. But if you're new to chemical vapor deposition (CVD) coatings, you probably have questions before placing an order. What materials can be coated? Will dimensions change? How do you prepare parts? What information should you provide for a quote?
At SilcoTek, our customer service team answers these questions every day. While every project is unique, there are a few common topics that can help make the process smoother and ensure you get the results you're expecting.
Which Coating Is Right for My Application?
One of the first questions customers ask is which coating they should choose. The answer depends entirely on the environment your parts will see and the problem you're trying to solve.
If your application requires an inert surface for analytical accuracy, a coating such as SilcoNert® may be the best option. If corrosion resistance is the primary concern, Dursan® may be a better fit. Other applications may benefit from wear resistant or conductive coatings.
You don't need to have all the answers before reaching out. In many cases, customers simply describe their application, operating conditions, and performance goals, and our technical team helps guide them toward the most appropriate solution.
What Information Should I Include in My Quote Request?
The more information you provide upfront, the faster we can evaluate your project.
Helpful details include:
-
Part drawings or dimensions
-
Base material
-
Operating temperature and environment
-
Chemicals or analytes the part will contact
-
Quantity of parts
-
Any critical surfaces
Even if you don't have all of this information available, sharing as much as possible allows our team to ask the right questions early and avoid delays later.
Can My Part Be Coated?
Many customers are surprised by the wide variety of parts that can be coated using SilcoTek's CVD process. Tubing, fittings, valves, sample cylinders, vessels, semiconductor components, filters, and custom machined parts are just a few examples.
That said, geometry matters. Internal diameters, blind holes, and extremely complex shapes may require additional review. The best approach is often to share drawings or photos with our team early in the process.
Will the Coating Change My Dimensions?
This is an especially important question for precision components.
SilcoTek coatings are extremely thin, typically measured in microns rather than mils. Because the coating is applied through a CVD process, it conforms to the shape of the part without significantly affecting dimensions or tolerances.
For customers working with tight specifications, our team can discuss expected coating thickness and help determine whether any special considerations are needed.

How Long Will The Coating Last?
This is one of the most common questions we receive, and understandably so. Customers want to know how long a coated component will perform in their specific environment before it needs to be replaced. The honest answer is that coating lifetime depends heavily on the application. Factors such as chemical exposure, temperature, pressure, concentration, flow conditions, and operating cycles can all influence performance over time.
Because every corrosive application is different, it is nearly impossible for us to provide a realistic estimate of coating life without real world testing. For this reason, SilcoTek recommends that all end users evaluate coated parts in their intended operating environment prior to full scale implementation. Testing allows customers to better understand coating performance, establish expected service life, and make informed decisions for critical applications where reliability is essential.
Our goal at SilcoTek is to partner with you to help you solve your corrosion problems, so we put a priority on helping you evaluate our coatings. This includes gathering relevant test data, providing samples, coating your test pieces, and putting our technical experts on your project to find a solution that works. Please contact us to discuss your application and establish a testing and validation plan.
What If I'm Not Sure Where to Start?
The good news is that you don't have to be an expert in coatings!
Many of our customers come to us with a problem rather than a coating specification. Maybe they're seeing corrosion in harsh environments. Maybe reactive compounds are disappearing during sampling. Maybe a process requires a cleaner, more inert surface.
Our job is to help translate those challenges into practical solutions.
The best technical customer service isn't simply answering questions. It's helping customers ask the right ones.

A Partnership Beyond the Purchase
At SilcoTek, customer service starts long before an order is placed. It means providing technical guidance, sharing application expertise, and helping customers understand their options so they can move forward with confidence.
Whether you're coating your first component or have been partnering with us for years, our goal remains the same: make the process easy, provide clear answers, and help you get the most from your coated parts.
