Electrostatic discharge (ESD) is a persistent challenge across almost every sector — from damaging microelectronics to creating ignition hazards in volatile environments. Traditional anti-static coatings and plastics often degrade, lose effectiveness, or require costly replacement. The ProShieldESD coating platform changes that. Built on a permanent, filler-free conductive polymer backbone, it delivers lasting static dissipative and conductive protection across industries and substrates.

But what makes ProShieldESD different is not just the science — it’s the breadth of its applications. This isn’t a single product, but a platform technology adaptable to open-ended chemistries and surfaces.

Why Applications Matter

Every industry faces unique ESD risks:
• In electronics, a single static event can ruin sensitive components.
• In aerospace and defence, static sparks can threaten mission-critical systems.
• In logistics, packaging must perform consistently across global humidity changes.

With ProShieldESD, one platform solves all these challenges — without fillers, reapplication cycles, or expensive engineered plastics.

When it comes to static control, consistency is everything. A solution that works well in one area but fails in another is no protection at all. That’s why the concept of homogeneous performance—uniform conductivity across every surface—is critical in modern industries.

From electronics manufacturing to medical devices, aerospace, and automotive systems, the demand for reliable, permanent static protection has never been higher. Yet traditional options—whether carbon-filled coatings or moulded ESD boxes—struggle to deliver true uniformity.

Why Consistency Matters in Static Control

Even the smallest gap in conductivity creates a weak point where electrostatic discharge (ESD) can occur. Sensitive components can be destroyed by as little as 30 volts—far below what humans can feel. Without uniform protection, businesses face:

• Product failures from hidden ESD damage
• Costly downtime caused by rework and repairs
• Quality issues that undermine reliability and compliance

The Problem with Fillers and Moulded Boxes

Carbon and metal-filled coatings are prone to clumping, settling, and uneven distribution. This creates patchy coverage and inconsistent results. Over time, fillers can migrate or flake, leading to contamination in sensitive environments.

Molded ESD boxes and plastics come with their own challenges. Conductivity is uneven throughout the material, surfaces wear with use, and designs are limited to fixed shapes. These parts often degrade, forcing replacements that add cost and waste.

The result? Solutions that look effective on the surface but fail under real-world conditions.

Homogeneous Performance with ProShield ESD

ProShield ESD is engineered to deliver truly homogeneous dissipative performance across a wide range of substrates—including plastics, foams, packaging, and floors. Unlike filler-based paints or molded boxes, it provides:

• Uniform static protection with no weak spots
• Permanent conductivity that doesn’t degrade over time
• No contamination risks from fillers or additives
• Flexible use across substrates—beyond the limits of moldings
• Low-cost, sustainable performance across diverse applications

Consistency = Reliability

In industries where reliability is non-negotiable, homogeneous performance isn’t just a feature—it’s a requirement. By delivering uniform, permanent ESD protection, ProShield ESD ensures every surface, every time, is protected.

Conclusion: The Future Is Consistent

The science of consistency shows that homogeneous performance is the foundation of effective static control. With ProShield ESD, businesses can finally eliminate the risks of patchy coatings and limited moulded solutions—achieving permanent, low-cost protection that’s as reliable as it is sustainable.

For decades, industries have turned to carbon and metal-based paints and molded solutions as a way to manage electrostatic discharge (ESD). These approaches rely on conductive fillers—such as carbon black, graphite, or metal powders—to provide static dissipation. At first glance, they seem effective. But in practice, both filler-based coatings and molded products create more problems than they solve, which is why solutions like ProShield ESD filler-free dissipative coating are redefining static control.

Modern electronics, medical devices, and aerospace systems demand permanent, reliable static protection. Traditional filler-based paints and moulded carbon boxes simply can’t keep up.

The Problem with Carbon and Metal Fillers & Moldings

1. Inconsistent Conductivity

Fillers rarely disperse evenly across a coating, and molded parts degrade over time. Both create patchy conductivity, leaving “weak spots” where ESD can build up and cause damage.

2. Performance Degradation

In coatings, fillers migrate, clump, or lose effectiveness; in molded parts, conductivity decreases as surfaces wear. What starts as protection becomes unreliable, requiring costly replacements or recoats.

3. Risk of Contamination

Carbon and metal particles can shed from coatings or molded items, contaminating sensitive environments. In sectors like electronics or medical devices, this poses serious compliance and safety risks.

4. Poor Substrate Compatibility

Filler-based coatings often fail on plastics, foams, or packaging, while molded solutions are limited in shape and application. Both restrict flexibility and service life.

5. High Lifecycle Costs

Between frequent recoating, replacing molded products, downtime, and labour, the hidden costs quickly add up. Although they may appear affordable upfront, traditional solutions become expensive to maintain.

The Smarter Alternative: ProShieldESD

Unlike traditional paints or molded products, ProShield ESD achieves uniform, permanent dissipative protection without relying on carbon or metal fillers.

• Permanent protection – no reapplication or replacement required
• Low-cost alternative to expensive paints and molded solutions
• No contamination risks from loose particles
• Wide substrate compatibility – works on plastics, foams, packaging, and floors
• Sustainable – less waste, fewer resources

The Future of Static Control

As industries demand greater reliability, flexibility, and sustainability, filler-based coatings and molded ESD products are no longer fit for purpose. They fail in performance, cost, and compliance.

ProShield ESD sets a new benchmark: permanent, low-cost static protection that replaces both paints and molded solutions—delivering a cleaner, smarter way forward.

Adhesion is one of the most critical factors in achieving reliable conformal coating performance. Even the most advanced coating—such as Parylene—can fail if it doesn’t bond strongly to the underlying surface. That’s where adhesion promoters come in.

At SCH Services Ltd, we supply and use several types of adhesion promoters, each tailored to different substrate materials. Choosing the right one ensures a strong bond and long-term reliability.

Why Adhesion Promoters Are Needed

Some substrates, such as smooth metals, plastics, or low-surface-energy materials, naturally resist coating adhesion. Without treatment, coatings may:
– Peel or flake over time
– Fail cross-hatch adhesion testing (ISO 2409)
– Compromise moisture or chemical protection

Adhesion promoters modify the surface to increase its surface energy, creating an interface that coatings can lock onto.

How Adhesion Promoters Work

Adhesion promoters typically work by:
– Chemically reacting with the substrate to create a stable bond layer.
– Roughening or activating the surface to increase surface energy.
– Forming a bridge between the substrate and coating for long-term durability.

When applied correctly, they significantly reduce the risk of delamination, even at higher coating thicknesses or in harsh environments.

Different Promoters for Different Substrates

There is no “one-size-fits-all” solution. At SCH Services Ltd, we offer a range of adhesion promoters designed for:
– Metals – to overcome smooth or oxidised surfaces.
– Plastics – especially low-energy substrates like polyethylene or polypropylene.
– Ceramics & Glass – to ensure strong bonds despite non-porous surfaces.
– PCB Materials – optimised for solder masks and copper traces.

By matching the promoter to the substrate, we ensure the coating achieves reliable, long-lasting adhesion.

SCH Services Ltd: Expertise in Adhesion Solutions

Whether you need Parylene, acrylic, urethane, or silicone coatings, SCH Services Ltd has the right adhesion promoter for your application. Because we use these promoters in our own coating services every day, you can trust that the solutions we supply are proven in real production environments.

When it comes to conformal coatings, adhesion is everything. A coating may offer excellent barrier protection, but if it delaminates or peels away from the surface, performance and reliability are instantly compromised. In the world of Parylene coatings, one question often raised is whether adhesion decreases as the coating thickness increases.

Understanding Parylene Deposition

Parylene is applied through a unique vapor deposition process, creating a pinhole-free, uniform layer. Unlike brush, dip, or spray coatings, this process ensures that every surface—flat, sharp-edged, or recessed—is covered evenly.

However, like all coatings, adhesion depends on both the substrate preparation and the thickness of the coating.

The Relationship Between Thickness and Adhesion

In general, thinner Parylene films (e.g., 2–5 μm) demonstrate the best adhesion because the stresses within the coating remain low. As the thickness increases—sometimes up to 50 μm or beyond—internal stresses in the polymer can build up. This may lead to reduced adhesion if the surface is not properly prepared.

The key factor is not just thickness but the surface energy and cleanliness of the substrate:
– Smooth, untreated surfaces can cause poor adhesion regardless of thickness.
– Surface activation (e.g., plasma treatment) dramatically improves adhesion across all thicknesses.
– On well-prepared surfaces, even thick Parylene coatings can achieve excellent adhesion and long-term reliability.

Best Practices for Strong Adhesion

To maintain adhesion across different thicknesses:
– Use surface pre-treatments such as plasma cleaning or adhesion promoters.
– Match coating thickness to application needs—don’t overcoat unnecessarily.
– Validate adhesion using industry standards such as cross-hatch adhesion testing (ISO 2409).

SCH Services Ltd: Expertise in Parylene Performance

At SCH Services Ltd, we understand how coating thickness impacts performance. We combine expert surface preparation with advanced deposition techniques to ensure Parylene adhesion remains strong at both thin and thick layers. Whether you require ultra-thin coatings for medical sensors or thick films for aerospace, our solutions deliver reliability without compromise.

When it comes to controlling electrostatic discharge (ESD), many industries have turned to ESD paints. These coatings are marketed as flexible enough to cover floors, ceilings, plastics, paper, cardboard, and foams, making them appear like a universal solution for static control.

But the reality is very different. While traditional paints may provide short-term conductivity, they degrade quickly, require frequent reapplication, and are very expensive compared to modern alternatives.

That’s why the concept of “lifetime dissipation” matters. With advanced coatings like ProShield ESD, businesses can achieve permanent static protection—without the costs and limitations of the traditional ESD paints.

The Problem with Traditional ESD Paints

Although they can be applied across a range of substrates—floors, ceilings, plastics, paper, cardboard, and foams—traditional paints suffer from serious flaws:

• Performance degradation – Fillers clump or separate, breaking the conductive path.
• Very expensive – High purchase price plus repeated reapplication.
• Maintenance downtime – Every recoat means disruption and extra labour.
• Contamination risks – Carbon or metal fillers can flake or contaminate sensitive environments.
• Hidden lifecycle costs – What looks cheap at first soon becomes costly.

What Does “Lifetime Dissipation” Really Mean?

Lifetime dissipation is the ability to provide continuous, uniform ESD protection across the entire life of the substrate—without needing to reapply the coating. If the coating can be seen it will be working and ensures:

• Permanent static protection on plastics, foams, cardboard, concrete, metals and more
• Reliable conductivity that doesn’t degrade
• Low-cost performance compared to expensive paints
• Wide compatibility with modern materials and applications

How ProShield ESD Delivers True Lifetime Dissipation

Unlike paints, ProShield ESD doesn’t rely on unstable fillers. Instead, it provides a uniform dissipative layer that remains effective across a wide variety of substrates, including plastics, foams, packaging, and flooring.

Key benefits:

• Permanent, maintenance-free protection
• Low-cost solution vs expensive ESD paints
• Versatile compatibility across plastics, foams, packaging & more
• Sustainable performance with less waste and downtime

Why Permanent Protection Matters

As electronics become smaller and more sensitive, a discharge of just 30 volts—far below human perception—can destroy them. Temporary coatings applied to floors, ceilings, or packaging can’t guarantee protection.

With ProShield ESD, businesses gain lifetime dissipation—a long-term, affordable, and reliable solution for modern industries.

Introduction

Conformal coating is vital for protecting electronics from moisture, dust, chemicals, and temperature extremes. Yet many manufacturers don’t have the facilities or expertise to manage coating in-house. That’s where subcontract conformal coating services—sometimes called outsourced conformal coating—play a critical role. By partnering with a specialist provider like SCH Services, companies gain expert support, cost efficiency, and consistent results without the burden of running their own coating line.

What Are Subcontract Conformal Coating Services?

Subcontract conformal coating means entrusting your printed circuit board (PCB) assemblies to an external, professional coating house. Instead of purchasing capital equipment, training staff, and maintaining coating systems, you send your assemblies to a contract conformal coating provider who applies the specified finish and returns them production-ready.

At SCH Services, we manage the full process:

• Intake & documentation
• Masking & preparation
• Application by spray, dip, or brush
• Curing & drying

All processes are carried out under ISO 9001 and ISO 14001 certified conditions, ensuring consistency and traceability.

Why Do They Matter?

• Expertise and Precision – Dedicated coating houses like SCH specialise in conformal coating. This focus means fewer defects, better adhesion, and compliance with IPC and MIL standards.
• No Need for In-House Experts – Hiring and retaining skilled conformal coating technicians can be difficult and costly. By subcontracting, you eliminate the need to recruit, train, and manage coating specialists in-house—your provider already has the expertise.
• Cost Efficiency – Outsourcing avoids the capital expense of equipment and staff. Subcontracting transforms fixed overhead into a flexible, predictable service cost.
• Speed and Flexibility – Professional coating partners can scale quickly, whether you need a handful of prototypes or high-volume production batches.
• Reduced Risk – Working with an established provider reduces the chance of coating failures, warranty claims, or costly rework.
• Compliance and Reliability – With certified processes and audited standards, subcontract conformal coating services ensure your electronics meet customer and regulatory requirements.

When Should You Consider Outsourcing?

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.
