Parylene Coating Services
European and Asian Parylene coating services through one controlled SCH process platform
SCH provides Parylene coating services for customers who need thin, conformal, vapour-deposited protection for electronics, sensors, medical devices, aerospace assemblies and precision components.
Our service model combines European coating services from SCH UK, India-based coating services for Asia and high-volume production, and a third specialist 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.
Parylene is not just a coating material. It is a controlled vacuum deposition process where grade selection, surface preparation, masking, loading, chamber behaviour and inspection all influence the final result.
SCH supports the main commercial chemistries including Parylene N, C, D and AF-4, helping customers match coating performance to geometry, dielectric requirements, environmental exposure, masking risk and production expectations.
Parylene coating services support prototype, qualification and production work where thin, conformal vapour-deposited protection is required.

Choose the Right Parylene Coating Service Route
Different Parylene projects need different levels of support. Some customers need subcontract coating for prototypes or production. Others need feasibility review, specification support, or a staged route towards in-house capability.
Subcontract Parylene Coating
Use SCH when you need prototype, qualification or production Parylene coating without investing in your own deposition line.
Feasibility and Specification Review
Use SCH when you are unsure which grade, thickness, masking route or acceptance criteria should be defined before coating.
India Services for Asia and Volume
Use SCH India for Asian regional coating services and high-volume production while retaining aligned SOPs, materials, machines and process controls.
Outsource-to-In-House Implementation
Use SCH when Parylene may become a core production process and you need equipment, dimer supply, training, documentation and implementation support.
UK, Europe, India and Asia Parylene Coating Capability
SCH provides Parylene coating services through a controlled international model. This gives customers regional flexibility without treating each site as a separate process island.

When Parylene Is the Right Answer
Parylene is strongest where the application needs thin, highly conformal, vapour-deposited protection across exposed surfaces and complex geometry.
- Fine-feature assemblies where uniform coverage is critical
- Electronics requiring thin dielectric and moisture barrier protection
- Sensors, medical devices and high-reliability components
- Assemblies where liquid flow, pooling or meniscus behaviour would create risk
- Applications where coating thickness must be tightly controlled
- Parts where regional coating supply or high-volume production economics need to be considered early

When Parylene Needs Careful Review
Parylene can be extremely effective, but it is not automatically the easiest or lowest-cost answer. It should be reviewed carefully when the assembly contains difficult masking zones, connector interfaces, rework requirements, qualification constraints or cost-sensitive production targets.
- Masking: exposed connectors, contacts, threads, mating surfaces and test points may need precise exclusion.
- Rework: Parylene removal normally requires specialist methods such as micro-abrasion, plasma or laser routes.
- Specification: vague notes such as โapply Paryleneโ are not enough for controlled production.
- Throughput and cost: vacuum deposition must be matched to batch size, thickness target and production economics.
- Process control: surface condition, loading and chamber stability strongly influence final quality.
- Production location: European, Asian, China-based or in-house production routes should be considered before qualification is locked.

Need More Than a Coating House?
Many customers begin with subcontract coating, then later decide whether to stay outsourced, move Parylene in-house, use India for volume, or adopt a hybrid model. SCH supports all of these routes.
If you need the bigger picture around implementation, equipment planning, dimer selection, training and long-term support, see our dedicated Turnkey Parylene Implementation & Support page.

Outsourcing vs In-House Parylene Coating
Every business has different needs when it comes to Parylene coating services. Many customers start by outsourcing coating to SCH to control risk, validate designs and build a business case before investing in their own line.
Why outsource Parylene coating services?
- No capital investment in Parylene equipment, vacuum systems and facilities
- Immediate access for prototypes, qualification lots and production jobs
- Process experience from SCHโs coating and reliability background
- Scalable support for one-off jobs, recurring batches or full programmes
- Reduced staffing, training, health and safety and maintenance burden
- Ability to compare UK, India, China partner and in-house production routes
Outsourcing to SCH is a low-risk way to benefit from Parylene coating services without committing internal resources from day one.
If Parylene later becomes a core part of your strategy and you want to explore in-house capability, our Parylene Solutions hub covers equipment, dimers, consumables and training, while our Turnkey Implementation page explains how customers typically move from outsourced coating into hybrid or in-house models.
