When it comes to protecting modern electronics and critical components, the greatest threats are often the ones you can’t see. Microscopic cracks, invisible moisture, and environmental contaminants all pose silent risks to performance and reliability. That’s where Parylene coating steps in—acting as an invisible shield that ensures long-term durability.

The Power of Parylene Coating

Unlike traditional conformal coating methods that are brushed, dipped, or sprayed, Parylene is applied through a unique vapor deposition process. This allows the coating to form a pinhole-free, uniform layer that covers every surface—even complex geometries and hidden crevices.

The result? A truly conformal barrier that doesn’t just coat what’s visible but also protects what lies beneath, in places you might never think to check.

Invisible Moisture Protection

Moisture is one of the most common culprits in electronic failure. Even the smallest amount of condensation can corrode circuitry or short sensitive components. Parylene offers unmatched moisture protection, creating a barrier that is far superior to liquid-applied coatings. Its microscopic film prevents water vapor ingress, ensuring components remain safe even in harsh or humid environments.

Why Industries Rely on Parylene

From aerospace and automotive to medical devices and consumer electronics, industries turn to Parylene because of its proven track record. It’s lightweight, biocompatible, chemically resistant, and highly reliable—making it the coating of choice when failure is simply not an option.

SCH Services Ltd: Your Partner in Invisible Protection

At SCH, we specialise in both liquid and Parylene conformal coating services, delivering solutions tailored to your application. Whether you need protection against moisture, chemicals, or long-term environmental stress, Parylene ensures that the unseen threats stay where they belong—out of your product.

Because the best protection is often the one you never notice.

Introduction: Why Parylene Stands Out

When it comes to protecting electronic assemblies, manufacturers have many conformal coating choices — acrylics, silicones, urethanes, and epoxies. But when performance and reliability cannot be compromised, Parylene stands apart as the industry benchmark.

At SCH Ltd, we are your complete one-stop partner for all Parylene needs. Unlike providers focused on just one area, we offer the full package: coating services, advanced deposition systems, high-purity dimers, consumables, spares, consultancy, and training.

Whether you’re outsourcing coatings, building in-house capability, or strengthening your supply chain, SCH provides the expertise and resources to make it happen. From our UK base, we deliver reliable end-to-end solutions for electronics, aerospace, automotive, and medical applications.

Our mission is simple: dependable, cost-effective, and scalable results—backed by the experience, infrastructure, and technical knowledge that make SCH the trusted name in Parylene.

Here are five reasons why Parylene is considered the gold standard.

1. Superior Barrier Protection

Parylene creates an ultra-thin, pinhole-free film that acts as a complete barrier against:

• Moisture and humidity
• Corrosive chemicals and solvents
• Salt spray and harsh environments

Unlike liquid coatings, Parylene is applied in vapour form, ensuring coverage even in crevices, under components, and around sharp edges. This uniform protection dramatically improves PCB reliability.

2. Uniform, Conformal Coverage

Because Parylene is deposited molecule by molecule in a vacuum chamber, the coating is:

• Perfectly uniform – even across complex 3D geometries
• Ultra-thin – typically 10–50 microns, avoiding weight or space issues
• Stress-free – no bridging or pooling, unlike liquid coatings

This makes it ideal for miniaturised electronics and dense assemblies where other coatings can’t reach.

3. Outstanding Chemical & Moisture Resistance

Parylene has excellent resistance to:

• Water vapour transmission
• Solvents and fuels
• Acidic and alkaline solutions

In industries like automotive (engine control units) or industrial electronics, where exposure to aggressive chemicals is common, Parylene provides unmatched long-term stability.

4. Biocompatibility for Medical Applications

One of the biggest advantages of Parylene is its biocompatibility. Certified to ISO 10993 standards, Parylene coatings are:

• Safe for direct contact with human tissue and fluids
• Widely used in implantable devices such as pacemakers and stents
• Common in diagnostics, wearable tech, and medical sensors

For medical manufacturers, Parylene isn’t just a coating – it’s a compliance pathway that allows devices to pass stringent regulatory requirements.

5. Long-Term Reliability in Harsh Environments

Parylene remains stable across a wide temperature range (-200°C to +150°C), resists UV degradation, and provides dielectric strength for sensitive circuits.

This durability makes it the coating of choice in:

• Aerospace & defence – avionics, satellites, radar systems
• Automotive – EV batteries, ADAS sensors
• Telecoms & IoT – outdoor and remote installations

When downtime isn’t an option, Parylene ensures electronics last.

When to Choose Parylene vs. Other Coatings

While Parylene is the best option for many high-reliability applications, it isn’t always the most economical for low-cost consumer products. Other coatings may suffice when:

• High chemical resistance isn’t needed
• Miniaturisation isn’t an issue
• Repairability is important

However, when failure isn’t an option, Parylene is the safe choice.

Conclusion: The Benchmark for Reliability

From medical implants to aerospace electronics, Parylene has earned its reputation as the gold standard in conformal coating. Its unique deposition process delivers uniform, durable, and biocompatible protection that liquid coatings simply can’t match.

SCH Ltd is your one-stop partner for Parylene, delivering coating services, deposition equipment, dimers, consumables, spares, consultancy, and training.

From our UK base, we provide scalable, cost-effective solutions trusted across electronics, aerospace, automotive, and medical industries.

In the world of electronics and advanced manufacturing, protecting sensitive components from moisture, chemicals, and environmental stress is critical. Conformal coatings play a vital role in ensuring reliability, but not all coatings are created equal. Among them, Parylene stands out as a unique and highly effective solution.

What Is Parylene?

Parylene is a family of thin, transparent polymer coatings applied through a chemical vapour deposition (CVD) process. Unlike liquid conformal coatings, which are sprayed, brushed, or dipped, Parylene is deposited as a vapour. This means it coats every surface — external and internal — with a uniform, pinhole-free layer.

The most common types of Parylene are:
– Parylene N: Excellent dielectric properties, used for high-frequency applications.
– Parylene C: The most widely used, with outstanding moisture and chemical resistance.
– Parylene F (AF-4): High-temperature and chemical resistance.

How Parylene Differs From Other Conformal Coatings

1. Application Method: Parylene is applied in a vacuum chamber as a vapour, ensuring complete and even coverage without pooling, meniscus effects, or edge build-up.

2. Coverage: Parylene can coat the inside of tight gaps, under components, and into complex geometries that liquid coatings cannot reach.

3. Film Properties: The coating is ultra-thin (typically 1–50 µm), transparent, flexible, and biocompatible.

4. Performance: Parylene offers superior resistance to moisture, chemicals, and extreme temperatures.

5. Cleanliness: As a dry, vapour-deposited coating, Parylene leaves no residues or solvents, making it ideal for sensitive applications such as medical implants and aerospace electronics.

Where Is Parylene Used?

– Medical devices: Catheters, stents, pacemakers, sensors.
– Aerospace and defence: Flight electronics, sensors, and high-reliability systems.
– Automotive: EV electronics, sensors, ADAS components.
– Consumer electronics: Wearables, IoT devices, and microelectronics.
