Top 10 Conformal Coating Suppliers in Ireland

Founded in 2008, Greenway Coatings has become a household name in Ireland's eco-conscious manufacturing scene. Walk into their Galway facility, and you'll notice something different: the air smells clean, not like harsh chemicals. That's because they specialize in water-based pcb conformal coating – a game-changer for companies prioritizing sustainability. "Traditional solvent-based coatings release harmful VOCs," explains Aoife Kearney, their technical director. "Our water-based formulas cut those emissions by 70%, and they perform just as well. Clients love that they can meet their green goals without sacrificing quality."

Greenway's sweet spot? Medical devices and consumer electronics. Their coatings are ISO 13485 certified (critical for medical gear) and RoHS compliant, making them a go-to for firms like Medtronic and Philips. They also offer custom formulations – recently, they developed a fast-drying acrylic blend for a Dublin startup making smart thermostats. "The startup needed a coating that could handle rapid production runs," Aoife says. "We tweaked our standard acrylic to dry in 30 minutes instead of two hours. Now they're shipping 5,000 units a month, and we're right there with them."

What sets them apart? Their "zero-waste" promise. They recycle excess coating, use energy-efficient curing ovens, and even offset their carbon footprint by planting trees in County Mayo. "Sustainability isn't a buzzword here," Aoife adds. "It's how we do business."

Emerald Electronics isn't just a supplier – they're a problem-solver. Tucked away in Dublin's Silicon Docks, this family-run firm has been tackling tough coating challenges since 1995. "We started with a single spray booth and a mission: to make coatings that work where others fail," says Liam Walsh, whose father founded the company. Today, their claim to fame is high-temperature silicone conformal coating, a specialty that's made them a favorite in the automotive and aerospace industries.

Why silicone? "Silicone can handle temperatures from -60°C to 200°C – perfect for car engines or jet turbines," Liam explains. "We had a client in Cork making sensors for race cars. Their PCBs were failing because the engine heat was melting standard coatings. We switched them to our silicone blend, and they haven't had a failure in two years." Emerald also offers parylene coating, a ultra-thin option for delicate components like sensors or LED arrays.

What makes them reliable? Their "24-hour rush" service. Need a batch of PCBs coated and shipped by morning? Emerald's team works around the clock to make it happen. "Last month, a client in Limerick had a production line down because their coating supplier missed a deadline," Liam recalls. "We picked up their PCBs at 5 PM, coated them overnight, and had them back by 8 AM. They still send us a thank-you card every Christmas."

If you're looking for a one-stop shop, Cork Conformal Solutions is your answer. Located in the heart of Cork's industrial estate, this supplier does it all: acrylic, silicone, urethane, even specialty parylene coatings. But their real pride and joy? Their acrylic conformal coating line. "Acrylics are the workhorses of the coating world," says technical lead Orlaith Duffy. "They're affordable, easy to apply, and if you ever need to rework a PCB – say, ｒｅｐｌａｃｅ a component – you can strip the acrylic with solvent and reapply. It's why they're popular for everything from power tools to home appliances."

Cork Conformal Solutions caters to both small startups and big manufacturers. For tiny runs (like 10 prototype PCBs), they offer manual spray booths with meticulous hand application. For mass production (10,000+ units), they use automated conveyor systems that coat 500 PCBs an hour. "We had a startup from Galway come to us with a single PCB for a smart garden sensor," Orlaith laughs. "Now they're shipping 20,000 units a quarter, and we're still their go-to. Watching clients grow – that's the best part."

They also invest heavily in training. Every technician goes through a 6-month certification program, and they host free workshops for clients on "Best Practices for PCB Coating." "Knowledge sharing isn't a loss – it's a gain," Orlaith says. "The better our clients understand coating, the better their PCBs turn out. It's a win-win."

Limerick Protective Coatings doesn't mess around when it comes to harsh environments. If your PCB is going into an oil rig, a mining machine, or a desert solar farm, this is the supplier for you. Their specialty? Urethane conformal coating, known for its toughness against chemicals, abrasion, and UV rays. "We had a client in Donegal making control panels for offshore wind turbines," says managing director Seamus O'Connor. "Saltwater, high winds, constant vibration – standard coatings were peeling off in months. We switched them to urethane, and those panels are still going strong after five years."

What sets Limerick apart is their testing lab. They don't just coat PCBs – they torture-test them. "We have chambers that simulate 500 hours of rain, 1,000 hours of UV exposure, even salt spray tests," Seamus explains. "If a client says, 'Will this coating work in the Sahara?' We don't guess – we put it in our heat chamber at 70°C with 10% humidity and see." This attention to detail has made them a trusted partner for firms in the energy and industrial sectors, including Siemens and ABB.

They're also pioneers in "hybrid" coatings – mixing acrylic and urethane for clients who need the best of both worlds. "A client making agricultural sensors wanted the repairability of acrylic but the chemical resistance of urethane," Seamus says. "We blended the two, and now it's our most requested custom coating."

Cross the border to Belfast, and you'll find Belfast Conformal Tech, a supplier with a focus on medical and healthcare electronics. Why medical? "Medical PCBs have zero room for error," says founder Declan McGrath. "A pacemaker's PCB can't fail because of moisture. A diagnostic machine's board can't short-circuit because of dust. That's why we specialize in biocompatible coatings and strict quality control."

Their coatings meet ISO 10993 (biocompatibility) and ISO 13485 (medical device manufacturing) standards, and every batch comes with a detailed certificate of analysis. "We once had a client making a portable ultrasound machine," Declan recalls. "Their PCB had to be waterproof enough to withstand being wiped down with disinfectant 50 times a day. We tested 12 different coatings before landing on a silicone-urethane blend that worked. Now, that machine is used in hospitals across Europe."

Belfast Conformal Tech also offers low-volume runs, a boon for startups in the medtech space. "Most suppliers want to coat 1,000+ PCBs at a time," Declan says. "We'll do 10. We remember what it's like to be a startup, scraping together funds for prototypes. We don't want coating to be a barrier."

Mayo Coatings & Services is proof that you don't need a big city location to be a top supplier. Tucked away in Castlebar, this family-owned firm has built a reputation for personalized service and quick turnaround. "We're not a faceless corporation," says owner Siobhan Gallagher. "When you call, you get me or my brother, not a call center. Clients love that – they know we're invested in their success."

Mayo Coatings specializes in small to medium runs (100-5,000 PCBs) and offers a "same-week" guarantee for standard coatings. "A client in Sligo needed 200 PCBs coated for a trade show demo in 3 days," Siobhan says. "We dropped everything, coated them overnight, and hand-delivered them. They won 'Best New Product' at the show – that's the kind of win we live for."

Their most popular service? "Coating + Testing." After applying the conformal coating, they run basic continuity tests to ensure no components were damaged during application. "It's an extra step, but it gives clients peace of mind," Siobhan explains. "If we find an issue, we fix it before it leaves our shop. No surprises when they get the PCBs."

Shannon Advanced Coatings is where innovation meets coating. Located near Shannon Airport, this supplier is all about pushing the boundaries of what conformal coating can do. Their latest breakthrough? UV-curable acrylic conformal coating. "Traditional coatings take hours to dry," says R&D head Niamh Hogan. "UV-curable ones dry in seconds – literally, under a UV lamp. It's a game-changer for high-volume production."

Shannon works closely with clients to develop custom solutions. Recently, they partnered with a Dublin-based drone company to create a coating that's both lightweight and impact-resistant. "Drones crash – it's part of testing," Niamh laughs. "Their PCBs were failing because the coating would crack on impact. We added tiny rubber particles to our acrylic formula, and now the coating flexes instead of breaking. They're now using it in all their commercial drones."

They're also leaders in "green" innovation. Their water-based UV coatings have 90% less VOCs than solvent-based options, and they're working on a plant-based coating made from sugarcane byproducts. "The future of coating isn't just about protection – it's about sustainability," Niamh says. "We want to be the ones building that future."

Waterford Electronics Coatings has a simple philosophy: "Do one thing, and do it better than anyone else." For them, that "one thing" is silicone conformal coating for the automotive industry. "Cars are tough on PCBs," says operations manager Eoin Murphy. "Extreme temperatures, vibration, oil, salt – you name it. Silicone handles it all. That's why 80% of our clients are automotive suppliers, from Tier 1 companies like Continental to small firms making custom car alarms."

What makes their silicone stand out? It's formulated to resist "outgassing" – the release of tiny particles that can fog up headlights or damage sensors. "A client was having issues with their ADAS (Advanced Driver Assistance System) cameras fogging up," Eoin recalls. "Turns out, the coating on their PCBs was outgassing. We switched them to our low-outgassing silicone, and the problem vanished. Now they're a client for life."

Waterford also offers training for client teams. "We'll send a technician to your facility to teach your staff how to inspect coated PCBs," Eoin says. "Knowledge is power – the better you can spot issues early, the fewer headaches down the line."

Sligo Conformal Innovations is the new kid on the block, but they're already making waves. Founded in 2019 by two former coating technicians, this startup specializes in coating for "odd-shaped" PCBs – think curved boards for wearables, or 3D-printed PCBs with complex geometries. "Traditional coating methods (like dipping or spraying) miss spots on weirdly shaped PCBs," says co-founder Cian O'Rourke. "We use a electrostatic spray system that charges the coating particles, so they're drawn to the PCB like a magnet. No more missed spots."

They've quickly become a favorite among startups in the IoT and wearable tech space. "A client in Galway made a smart watch with a curved PCB," Cian says. "Other suppliers couldn't coat the edges without drips. We used our electrostatic system, and the coating was smooth as glass. Now their watch is selling in Europe and the US."

Despite being new, they're committed to quality. They're ISO 9001 certified and have a 24-hour response time for quotes. "We know startups don't have time to wait," Cian adds. "We'll give you a quote in a day, and turn around small runs in 48 hours. No red tape, just results."

Last but never least, Donegal Conformal Coatings rounds out our list with a focus on the basics: quality, reliability, and fair pricing. Located in Letterkenny, this supplier has been a staple for local manufacturers since 2001. "We don't chase fads," says owner Martin Boyle. "We stick to what works: high-quality acrylic and silicone coatings, applied by skilled technicians, at a price that won't break the bank."

Donegal serves a mix of industries, from agricultural machinery to marine electronics. "A local fishing boat manufacturer uses our silicone coating on their navigation PCBs," Martin says. "Saltwater is brutal, but their boards last 5+ years now. That's the kind of loyalty we build – one reliable coating at a time."

They also offer free samples – send them a PCB, and they'll coat it for free so you can test it before committing. "We want you to trust us," Martin explains. "If our coating doesn't work for your project, we'll tell you upfront. No hard sell, just honesty."
