Last week we discussed how to select a coating vendor. In this week's blog post we'll discuss standards and how coatings comply and in some cases don't comply with industry standards and applications.
SilcoTek® coatings are used in a wide variety of applications. Coating uses range from mold release, process sampling, semiconductor manufacturing, oil and gas production, hydrocarbon processing, analytical testing, GC, HPLC, medical diagnostics instrumentation and much more. Customers in these fields often ask how are the coatings used in test methods and do SilcoTek coatings comply with my industry standards? That's a valid question, so we rolled up our sleeves and dug through methods or applications that use our coatings. To be sure, there are many more applications and uses for our coatings, here are just a few on our list.
Do Silicon Coatings Meet Industry Standards? In this blog post you will learn:
Okay, first a bit of a disclaimer. The methods we're listing may not specifically call out our coatings, some methods specify a performance criteria that can only be achieved by using inert coatings, other times products featuring our coatings or equivalent are called out. Want to learn about our coatings and applications? Get our free coating e-books.
We searched methods and related products used in the method application to find industry approved or customer approved use of our coatings. For some applications we’re formally approved, in other uses we're referenced in tests or standards. Some applications call out a specific coated component either by our brand name or the customer brand. So we're casting a wide net to list as many standards and methods for various industries. Of course individual customers have their own approval process and methods which are not discussed. We don't list customer approved uses as they are confidential.
Do silicon coatings meet industry standards? Yes! Here are the many standards that specify our silicon coatings.
Refinery & Petrochemical / Spec Gas / Natural Gas / Oil & Gas Exploration
CVD coatings are used to line product sampling flow paths and are essential in environmental monitoring applications like flare, stack and fenceline monitoring. Inert coatings prevent reactive compounds like H2S from interacting with stainless steel surfaces. When reactive compounds interact with steel surfaces they're adsorbed into the flow path surface which results in lower readings or just plain incorrect results. This can be a huge deal for regulatory compliance or feedstock monitoring. Applicable standards our coating comply with are:

Benefits of using inert silicon coatings in hydrocarbon processing applications
- Faster response
- Accurate and reliable sulfur test results
- Faster calibration
- Fewer test failures
A standard we don't comply with
What about NACE standard MRO 175 (Materials for use in H2S containing environments)? Do SilcoTek coatings comply with this standard? No. MRO 175 specifies the base metals that are approved for H2S environments, not coatings. No coating will apply to MRO 175, only base metals. Our coatings when applied to MRO 175 approved metals will improve the surface inertness and improve H2S detection. The base metal will continue to comply with MRO 175. Applying our coatings to non compliant materials will not make them compliant, only inert to reactivity.
Medical and Pharmaceutical
Our coatings act as an inert barrier between the test sample and the flow path surface. The coatings prevent corrosion, cross contamination, and chemical adsorption. All benefits are geared toward improving test reliability and sensitivity. Our coatings are FDA compliant by meeting NSF standards.
- NSF Approval / ANSI 51 Compliance (Food equipment materials)
- FDA 21 CFR 211.65 (Pharmaceutical equipment)
- ISO 10993-5 (2009) (Bio compatibility testing)
Benefits to Medical and Pharma Testing
- Prevent chemical adsorption
- Reduce analyte carryover and contamination
- Prevent protein binding and sticking
- Improved flow path corrosion resistance

About Corrosion Resistance
Our coatings are also tested to various corrosion standards. In this case our coatings are not part of the test method, we're the focus of the testing. Since corrosion testing applies to many industries, we thought it would be beneficial to list some of the methods used to evaluate our coatings for corrosion resistance. Our coatings have been successfully tested for corrosion resistance using the following standards:
- ASTM G85, Salt Spray
- ASTM B117, Salt Spray
- ASTM G85-A2, Acidified Salt Spray
- ASTM G31, Immersion Testing
- ASTM G48, Method B2 – ferric chloride pitting and crevice corrosion
- ASTM D4585, condensing humidity
Corrosion resistance benefits
- Extend the life of existing components
- Improve corrosion performance using existing materials and design
- High tolerance coating does not alter part fit or geometry
