Even the best Parylene coating cannot perform reliably if the surface beneath it is not properly prepared. Adhesion failures, delamination, and reduced barrier performance often trace back to poor substrate preparation. That’s why surface preparation is one of the most critical steps before Parylene deposition.

Parylene is applied via vapor deposition, forming a thin, uniform layer that reaches every exposed surface. However, if the substrate has contamination, low surface energy, or residues, the Parylene may not bond properly—resulting in peeling, flaking, or reduced adhesion.

Correct preparation ensures:
– Strong coating adhesion
– Reliable moisture and chemical protection
– Consistent long-term performance

Cleaning: Removing Contaminants

Before applying adhesion promoters, thorough cleaning is essential. Residues like flux, oils, or dust can prevent the coating from bonding properly. Techniques include:
– Solvent cleaning for organic residues
– Ultrasonic cleaning for precision components
– Controlled drying to avoid recontamination

Adhesion Promoters: Creating Reliable Bonding Sites

Adhesion promoters (such as silane-based primers) are widely used to enhance Parylene’s bonding strength. These chemical agents modify the substrate surface to create functional groups that improve adhesion. They are particularly effective on low-energy materials such as plastics, ceramics, or glass, ensuring Parylene bonds securely and permanently.

By combining effective cleaning with adhesion promoters, manufacturers can achieve optimal performance, preventing delamination and ensuring coatings that last.

SCH Services Ltd: Proven Preparation and Coating Expertise

At SCH Services Ltd, we combine cleaning and adhesion promoter treatments with expert Parylene deposition to deliver coatings that bond reliably across all substrates. Because we apply these techniques in our own coating services, customers benefit from proven processes designed for maximum performance.

Electrostatic discharge (ESD) protection is non-negotiable in industries such as electronics manufacturing, aerospace, automotive, and medical devices. For decades, two common approaches have dominated: molded ESD solutions (like carbon-filled boxes) and filler-based ESD paints. On paper, both seemed like effective answers. In practice, they’ve proven costly, inconsistent, and difficult to scale.

At SCH Services, we experienced these frustrations first-hand. That’s why we created ProShield ESD—a permanent, polymer-based dissipative coating that replaces outdated molded and filler-based technologies once and for all.

The Problems with Traditional ESD Solutions

1. Molded Carbon Boxes and Plastics

Carbon-filled molded solutions are heavy, expensive to produce, and limited to specific applications. Their conductivity degrades over time, and the one-size-fits-all approach leaves little flexibility for custom requirements.

2. Filler-Based ESD Paints

Most ESD paints rely on carbon or metal fillers for conductivity. These fillers wear down, clump, or flake, creating patchy protection, contamination risks, and compliance issues in sensitive environments. The paints themselves are expensive—and frequent reapplication only multiplies lifecycle costs.

3. Limited Versatility

Neither molded boxes nor traditional paints perform well across diverse substrates such as plastics, foams, packaging, or floors, making it hard to standardise static protection throughout a facility.

How We Solved It with ProShield ESD

When it comes to protecting sensitive electronics, medical devices, and mission-critical components, the choice of coating can define long-term performance. Two common options are Parylene coating and traditional conformal coatings such as acrylics, silicones, and urethanes. Each offers unique benefits, but which is right for your application?

What Makes Parylene Different?

Parylene is applied using a vapor deposition process, producing a pinhole-free, uniform film that coats every surface—even hidden spaces and complex geometries.

This process ensures:
– Exceptional moisture protection
– Ultra-thin yet highly durable barriers
– Strong resistance to chemicals, solvents, and extreme temperatures

Because it forms a truly conformal layer, Parylene is often the choice where reliability cannot be compromised.

Where Traditional Coatings Excel

Traditional conformal coatings are applied by brushing, spraying, or dipping. They remain highly effective in many environments and offer advantages such as:
– Faster application and curing
– Lower cost compared to Parylene
– Easy rework and repair during production

For applications where cost sensitivity or rapid turnaround is key, traditional coatings remain a strong solution.

Making the Right Choice

The decision depends on your product’s environment and performance requirements. If your device must endure harsh conditions, Parylene provides unmatched protection. For less demanding applications, traditional coatings may strike the right balance between performance and budget.

SCH Services Ltd: Your Coating Partner

At SCH Services Ltd, we provide both Parylene and liquid conformal coating solutions—helping you choose the right option for your project. Whether you need high-performance protection or cost-effective coverage, our expertise ensures your product is protected for the long term.

In modern electronics and high-reliability assemblies, one of the most overlooked yet critical steps is masking—protecting areas that should not be coated during the conformal coating process. Done poorly, masking becomes a bottleneck: misalignment, rework, and delays can cripple throughput. But with custom pre-cut masking shapes, you can turn that bottleneck into a breakthrough.

The Masking Challenge

When applying conformal coatings or advanced materials like Parylene, every pad, connector, or sensor must be protected precisely. Traditional manual cutting of tape is slow, inconsistent, and often unreliable.

The result?
– Masking residue left behind
– Shrinkage or degradation under solvents
– De-wetting caused by silicone contamination
– Tape lifting or bleeding into protected areas

These issues reduce yield, increase rework, and slow down production.

 The Advantage of Custom Masking Shapes

At SCH Services Ltd, we provide custom masking shapes designed specifically for conformal coating processes—including our own coating services. By using the same solutions we supply to our customers, we ensure accuracy, consistency, and quality at every stage.

Benefits of custom shapes include:
– Residue-free removal with no damage to components
– Solvent and chemical resistance for use in harsh environments
– Silicone-free materials to avoid contamination and coating defects
– Clean, reliable adhesion that prevents bleeding or lifting
– Ready-to-use sheets for fast application and reduced operator time

Because we rely on these shapes daily in our own conformal coating services, we know firsthand how they improve throughput, reduce defects, and eliminate bottlenecks.

 From Bottleneck to Breakthrough

Here’s how custom masking shapes change the game:

By standardising masking with custom shapes, conformal coating production flows faster, more reliably, and with fewer errors.

 SCH Services Ltd: Proven in Our Own Services

Unlike suppliers who only sell materials, SCH Services Ltd actively uses these custom masking shapes in our own conformal and Parylene coating services. This means our products are proven daily in real production environments. Customers benefit from the same quality, speed, and precision we demand for our own clients.

When reliability matters, masking isn’t a bottleneck—it’s a breakthrough.

In today’s high-tech world, static electricity is more than just a small spark—it’s a multi-million-pound risk. From advanced electronics manufacturing to medical devices, automotive systems, aerospace, and logistics, electrostatic discharge (ESD) can damage components, disrupt production, and threaten both safety and reliability. Effective static control has never been more critical.

The Hidden Threat of Electrostatic Discharge (ESD)

Electrostatic discharge occurs when two objects with different electrical charges come into contact or close proximity. While the human body may only notice a static shock at 3,000 volts or more, sensitive electronic components can be destroyed by as little as 30 volts. With today’s microelectronics becoming smaller and more powerful, their tolerance for ESD is dropping—making robust ESD protection essential.

Costly Consequences Across Industries

• Electronics Manufacturing – Static discharge can silently damage semiconductors, leading to latent failures and costly product recalls.
• Automotive & Aerospace – Modern vehicles and aircraft rely heavily on electronics; ESD-related faults can compromise safety and performance.
• Medical Devices – From pacemakers to diagnostic equipment, reliability is paramount. Static control for medical devices prevents life-threatening failures.
• Logistics & Packaging – ESD-safe packaging and handling reduce risks during storage and transport, while also preventing fire hazards in volatile environments.

Why Static Control Is More Urgent Than Ever

• Miniaturisation of Components – Smaller circuits are more sensitive, leaving no margin for uncontrolled discharges.
• Global Supply Chains – Failures at any stage—manufacturing, shipping, or assembly—can cascade into costly disruptions.
• Safety & Compliance – Industries face stricter regulations and standards; effective static control solutions are no longer optional.
• Sustainability & Cost Reduction – Preventing waste through better ESD solutions reduces scrappage, rework, and environmental impact.

Modern Solutions for Static Control

Static control has evolved far beyond temporary sprays or metal fillers. Permanent, low-cost coatings such as ProShield ESD now provide uniform, reliable, and maintenance-free protection across a wide range of substrates—plastics, foams, floors, and packaging. This innovative approach ensures full lifecycle protection without degradation or costly reapplication.

Why We Are Different

Unlike traditional carbon or metal-filled paints, which degrade quickly and shed contaminants, ProShield ESD offers permanent, homogeneous dissipation without the drawbacks of fillers. Our coating is engineered to be low-cost, sustainable, and effective across multiple substrates—from plastics and foams to paper, cardboard, and flooring. This means fewer reapplications, lower lifecycle costs, and more reliable protection. By combining affordability with consistent long-term performance, ProShield ESD sets a new standard in modern static control.

Static control is not a one-time fix—it’s a long-term strategy. Businesses that prioritise effective ESD protection reduce downtime, cut costs, and protect their reputation for quality. In industries where precision, safety, and reliability are everything, controlling static isn’t just important—it’s mission-critical.

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.
