Advanced Functional Coatings for Electronics & Precision Components
Low-build coating strategies for surface control, selective protection, and application-led performance
This page is the top-level hub for SCHβs advanced functional coatings platform, linking application pathways, material strategies, and low-build coating routes for electronics and precision components.
Why Advanced Functional Coatings Are Used
Advanced functional coatings are used where traditional conformal coating or Parylene introduce limitations in thickness, masking complexity, or surface performance.
In many applications, the requirement is not increased coating thickness, but a controlled change in surface behaviour such as water repellency, oil resistance, contamination control, reduced fouling, or preservation of electrical and mechanical function.
These coatings typically operate at sub-micron to low micron thickness, modifying surface properties rather than forming a conventional barrier layer.
Where They Fit
This makes them particularly relevant where selective performance is required without excessive material build-up, complex masking, or the process constraints associated with thicker coating systems.
How This Fits Within SCHβs Coating Platform
Within SCHβs coating platform, advanced functional coatings sit alongside conformal coating services and Parylene coating solutions, forming part of a wider application-led coating strategy.
This page acts as a decision framework for selecting between hydrophobic, ultra-thin, PFAS-free, and nano coating routes, including practical execution paths such as LT Series, UVX, and OPX.
Advanced functional coatings are the broader decision framework, while nano coatings are one practical technology platform used to deliver many of these low-build surface performance routes.
The diagram below compares parylene coating, conformal coating, and advanced functional coatings, helping identify when barrier protection, general protection, or surface performance is the correct approach.

Where Advanced Functional Coatings Fit
Advanced functional coatings are not a replacement for Parylene or conformal coating. They solve different problems and should be selected based on application requirements rather than coating type alone.
Once it is clear that surface behaviourβnot barrier protectionβis the primary requirement, the next step is selecting the correct functional coating route.
Understanding Hydrophobic Behaviour
Hydrophobic performance is often misunderstood. Standard conformal coatings can provide moisture resistance without being truly water-repellent in terms of surface behaviour.
For a technical explanation of how hydrophobic coatings work, and how acrylic, nano, and hybrid systems compare, see our hydrophobic conformal coating guide.
Choosing the Right Functional Coating Route
The correct route becomes clear once the primary constraint is defined β surface behaviour, thickness limitation, regulatory requirement, or production process.
The diagram below helps identify the most appropriate pathway.
