They're also quick to adapt: during the 2021 global chip shortage, they introduced "coating-on-demand" services, allowing clients to coat PCBs as components became available, reducing inventory costs.
With a 24-hour turnaround for small batches and a dedicated R&D team, ElektroLayer is a favorite for startups and SMEs. "We don't just coat boards – we solve problems," says sales director Luka Horvat. "If a client needs a custom color for branding or a coating that resists marine salt spray, we'll develop it."
4. Dalmatian Protective Coatings (Split)
Dalmatian Protective Coatings (DPC) has built its reputation on
high-precision parylene coating
, a niche but critical service for aerospace and defense electronics. Based in Split, their team includes former aerospace engineers who understand the unique demands of these industries: extreme vibration, radiation, and long-term reliability (think 20+ year lifespans for satellite components).
DPC's parylene deposition system is one of only three in Southeast Europe, capable of coating PCBs as small as 0.5mm². They're certified to AS9100 (aerospace quality) and work closely with Croatian defense contractors and European space agencies. What's unique? Their "failure analysis" service: if a coated PCB fails in testing, their engineers trace the issue back to coating application, material defects, or design flaws – a level of support rare in the industry.
"Aerospace clients don't just want a coating – they want data," explains technical lead Ana Marić. "We provide full documentation: thickness maps, adhesion test results, and even X-ray scans of the coating's uniformity. It's overkill for some, but for a satellite, it's non-negotiable."
5. Zagreb PCB Coatings (Zagreb)
Zagreb PCB Coatings (ZPC) is all about
speed and scalability
. Catering to high-volume manufacturers in automotive, consumer electronics, and appliances, they've invested in automated coating lines that can process up to 5,000 PCBs per day. Their specialty?
Acrylic conformal coating, prized for its fast curing time (as little as 30 minutes) and ease of rework – perfect for mass production where efficiency is key.
ZPC's facility includes inline testing stations that check coating thickness (via laser micrometry) and coverage (using UV inspection) before boards leave the line, reducing defects to less than 0.1%. They're also a leader in
RoHS-compliant conformal coating
, ensuring all materials are free of lead, cadmium, and other restricted substances – a must for clients selling into the EU market.
"We measure our success in seconds," jokes operations manager Marko Jurić. "A 10-second delay in our line costs us 800 boards per day. That's why we've invested in AI-driven process optimization – our system adjusts spray nozzles and curing times in real time to keep up with demand."
6. Istrian Coating Services (Pula)
Tucked away in the coastal city of Pula, Istrian Coating Services (ICS) is a hidden gem for
low-volume, high-mix projects
. Unlike larger suppliers focused on mass production, ICS thrives on small batches, prototypes, and custom jobs – making them ideal for startups, universities, and R&D labs.
Their team of coating technicians has decades of experience with niche applications, from coating PCBs for underwater sensors (using silicone for flexibility) to art installations (clear acrylic to preserve aesthetics). They offer free sample coatings for new clients, allowing testing before committing to a full order. ICS is also one of the few Croatian suppliers with expertise in
conformal coating for PCBAs with sensitive components
, such as MEMS sensors and microcontrollers, where over-spray can damage delicate parts.
"We don't turn down 'weird' projects," says owner Petra Babić. "Last year, we coated PCBs for a robotics competition team – they needed something lightweight, heat-resistant, and pink. We delivered, and they won first place. That's the fun of working with small clients."
7. Slavonian Electronics Coatings (Osijek)
Slavonian Electronics Coatings (SEC) in Osijek specializes in
silicone conformal coating
, a material prized for its flexibility and resistance to extreme temperatures (-60°C to +200°C). This makes SEC a top choice for automotive under-the-hood components, industrial motors, and outdoor electronics like solar inverters.

They're also certified to ISO 14001 (environmental management), using water-based silicone carriers to reduce emissions.
"Silicone is a tricky material – too soft, and it wears off; too stiff, and it cracks," explains chemist Tomislav Novak. "Our formulations balance hardness and flexibility perfectly. Clients tell us our coatings outlast competitors by 30% in field tests."
8. Dubrovnik Precision Coatings (Dubrovnik)
Dubrovnik Precision Coatings (DPC) is a boutique supplier focusing on
medical and dental electronics
. With a cleanroom facility (Class 7) and ISO 13485 certification, they specialize in biocompatible coatings like parylene and urethane, ensuring PCBs in devices like dental drills and MRI machines are safe for human contact.
DPC's attention to detail is legendary. Each batch of coating material is tested for biocompatibility (per USP Class VI) before use, and every coated PCB comes with a traceability report linking it to raw material lots, operators, and test results. They also offer
post-coating sterilization support
, advising clients on how to sterilize devices (autoclave, EtO gas) without damaging the coating.
"In medical, there's no room for error," says quality manager Iva Šimić. "We once rejected an entire batch because a coating thickness was 0.5 microns below spec. The client was frustrated at first, but when their device passed FDA inspection with zero issues, they thanked us."
9. Rijeka Vapor Coatings (Rijeka)
Rijeka Vapor Coatings (RVC) is Croatia's only dedicated parylene coating supplier, offering vapor deposition services for clients who need the ultimate in protection. Parylene, applied as a gas, forms a pinhole-free, conformal layer that's thinner than a human hair but resistant to chemicals, moisture, and even nuclear radiation – making it ideal for military, aerospace, and high-end medical devices.
RVC's team includes parylene experts trained at the University of Dayton (a pioneer in parylene research), and their deposition chambers can handle PCBs up to 600mm x 600mm. They're also one of the few suppliers in Europe offering parylene N, C, and HT (high-temperature) variants, giving clients options for cost vs. performance.
"Parylene isn't cheap, but for critical applications, it's worth it," says technical director Josip Filipović. "We coated PCBs for a deep-sea exploration robot last year – it operated at 6,000 meters for three months, and the coatings were still intact when it returned. That's the power of parylene."
10. Croatian Coating Innovations (Zagreb)
Rounding out our list, Croatian Coating Innovations (CCI) is a forward-thinking supplier focused on
sustainable and smart coatings
. Their flagship product? A self-healing acrylic coating that repairs small scratches when exposed to heat (e.g., from the device's normal operation), extending PCB life in rugged environments.
CCI also leads in digital integration, offering clients a portal to track orders in real time, view quality reports, and request rework. They're certified to ISO 45001 (occupational health and safety) and use 100% renewable energy in their Zagreb facility, appealing to eco-conscious brands.
"The future of
conformal coating isn't just about protection – it's about intelligence," says founder Matej Karlić. "Our self-healing coating is just the start. Next year, we're launching a 'smart coating' with embedded sensors that alert users to coating degradation before it causes failures."
