Parylene Coating Solutions
European and Asian Parylene coating services through one controlled SCH process platform
At SCH Services Ltd, we provide complete Parylene coating solutions built around your product, production volume, qualification route and long-term control strategy.
Our Parylene platform combines European coating services from SCH UK, India-based coating services for Asia and high-volume production, and a third specialist production option through our Karynano partner route in China.
Both SCH UK and SCH India can support trials, process development, qualification work and production. The important point is control: both sites operate aligned SOPs, ISO-controlled quality systems, common process documentation, approved dimers, equivalent machines, shared engineering knowledge and aligned production controls.
Whether you need European coating support, Asian regional supply, high-volume cost-effective production, in-house equipment, or a hybrid model, SCH helps define a practical route that fits your technical, commercial and geographic requirements.
For broader comparison between conformal coating, Parylene and advanced functional coatings, see our coating selection guide.
Parylene coating pathway: define the route, control the process, validate the product and choose the right regional or volume production option.

One Global Parylene Platform
Parylene projects often fail commercially because coating supply, process knowledge, qualification support, regional logistics and production cost are treated separately. SCH brings these elements together into a single controlled coating platform across the UK, India and our China partner route.
SCH UK / Europe
European Parylene coating services, trials, qualification work, process development, customer support, audits, troubleshooting, documentation and specialist production.
SCH India / Asia and Volume
Parylene and liquid conformal coating services for Asia and high-volume production, using aligned SOPs, ISO systems, materials, machines, documentation and process controls.
China Partner Route
Additional specialist Parylene capacity through our Karynano partner route, giving customers a third option where China-based processing is appropriate.
This gives customers flexibility: use SCH UK for European programmes, SCH India for Asia and high-volume production, Karynano where China-based processing is appropriate, and maintain aligned SCH process control across the full programme.
Which Parylene Route Fits Your Business?
The best Parylene strategy depends on product maturity, volume, qualification status, internal resource, target cost and how much process control you want to own.
Outsource Coating
Use SCH for qualification batches, early production, overflow, specialist projects or long-term subcontract Parylene coating.
Use SCH India for Asia and Volume
Use SCH India for Asian regional coating services and high-volume production while retaining aligned documentation, SOPs, materials, machines and process controls.
Build In-House Capability
Install your own Parylene deposition system with equipment, materials, training and process support from SCH.
Use a Hybrid Model
Combine in-house control with SCH as your technical partner for backup capacity, overflow, new programmes and troubleshooting.
Subcontract Parylene Coating Services
Outsource today, scale globally tomorrow, and keep the process controlled.
Many customers start with subcontract Parylene coating to qualify designs, avoid capital spend, support early production or smooth out demand. SCH can support this through European coating services from the UK, India-based coating services for Asia and high-volume production, or a hybrid programme across both SCH sites.
Typical reasons to use SCH coating services include:
- Validating new products before capital investment at either SCH site
- Supporting European coating requirements through SCH UK
- Supporting Asian regional supply and high-volume production through SCH India
- Covering peaks in demand, overflow work or emergency capacity
- Preparing a stable process before transfer to an in-house line

Liquid Conformal Coating Services in the Same Global Model
SCH India also supports liquid conformal coating services for Asia and high-volume production, using the same process-led approach, SOP discipline, inspection methods and coating knowledge that support the wider SCH group.
This is particularly useful where customers need a practical balance between technical support, repeatable coating quality and competitive production cost.
Parylene Deposition Equipment
Turnkey lines designed around your products, not just a catalogue model.
When you are ready to bring Parylene in-house, SCH helps design and supply deposition equipment sized to your real workload. We focus on process layout, fixturing, masking, safety, maintenance, documentation and future expansion.
Our own coating operations give us practical insight into the decisions that affect production stability, including dimer loading, chamber capacity, masking strategy, adhesion control, fixture design, cleaning and inspection.

Consultancy, Training and Knowledge Transfer
We teach the process so your team can control it.
Training and consultancy are central to SCHโs solutions-based model. We help customers design processes, write work instructions, train operators and engineers, build control plans, and understand how Parylene behaves in real production.
This knowledge-transfer approach supports customers who outsource coating, scale production through India, install equipment in-house, or need SCH as a long-term technical backup provider.
For a deeper explanation of why operator knowledge and process control matter, read our Insight on why Parylene coating training is critical for process control and reliability.

Need to Control Parylene Process Risk?
Parylene performance depends on more than the coating grade. Masking, cleaning, adhesion control, fixturing, chamber stability, dimer loading, inspection and operator knowledge all influence whether the process becomes reliable in production.
Review the Parylene Process & Reliability Hub
If you are already qualifying parts, troubleshooting defects, planning European or Asian coating supply, evaluating high-volume production or considering in-house equipment, you can also discuss your Parylene requirement with SCH.
When Parylene May Not Be the Best Fit
If your application needs lower-cost production protection with easier rework, review our conformal coating solutions. If the requirement is ultra-thin hydrophobic behaviour, low surface energy or minimal dimensional impact, review our advanced functional coatings.
Parylene for Fine Metal Structures and Complex Micro-Geometries
Parylene is widely used on delicate metallic structures where ultra-thin, highly conformal protection is required without significantly affecting geometry or mass. This includes applications such as stent frames, fine wire structures, miniature components and other complex micro-featured assemblies.
For a practical overview of coating fine metallic geometries and difficult micro-structures, review our Insight on Parylene coating for stent frames and micro metal structures.
Parylene Solutions FAQs
What is Parylene and why is it used?
Parylene is an ultra-thin, vapour-deposited conformal coating used to protect electronics, medical devices and other high-value components. It is chosen when designers need a uniform barrier with minimal added mass, strong environmental protection and coverage in hard-to-reach areas.
Can SCH provide Parylene coating from India?
Yes. SCH India provides Parylene coating services for Asia and high-volume production from Hyderabad, supported by aligned SOPs, ISO-controlled quality systems, approved dimers, equivalent machines, shared documentation and aligned SCH process controls.
Is the India process different from the UK process?
The intended advantage is regional access, logistics and production economics, not uncontrolled process variation. Both SCH UK and SCH India can support trials, qualification work and production using aligned SOPs, common process documentation, approved materials, equivalent machines, shared engineering knowledge and aligned production controls.
What role does Karynano play?
Karynano provides an additional China-based partner route for specialist Parylene capacity where China processing is technically, commercially or geographically appropriate.
Should we outsource Parylene coating or bring it in-house?
That depends on volume, product maturity, quality requirements, internal engineering bandwidth and how much process control you want to own. Many customers start with subcontract coating, then move to in-house equipment once demand, learning and justification are strong enough. Others stay hybrid and use SCH for backup, overflow and new programme support.
What Parylene grades does SCH support?
SCH supports the main commercial grades including Parylene N, C, D and AF-4. The right choice depends on dielectric performance, moisture barrier requirements, temperature exposure, chemical resistance and cost objectives.
Can SCH supply more than just coating services?
Yes. SCH provides a broader Parylene platform including coating services, equipment, dimers, consumables, spares, training and structured knowledge transfer.
