"Our goal is to make green manufacturing accessible, even for small batches." Whether you're prototyping a smart home sensor or scaling up production for a new wearable device, LPC offers scalable solutions that grow with your business.
Why work with two suppliers when you can work with one? Maribor Coating Experts, founded in 2002, has made a name for itself by offering end-to-end PCB protection solutions: conformal coating plus in-house testing services. Based in Maribor, Slovenia's second-largest city, the company operates a fully equipped testing lab where they perform environmental stress tests (temperature cycling, humidity resistance), adhesion tests, and dielectric strength checks—giving clients peace of mind that their coated PCBs will perform as expected in real-world conditions.
Maribor's client roster includes major players in telecommunications and energy, where PCB reliability is mission-critical. For example, they recently partnered with a leading energy company to coat PCBs for wind turbine control systems, ensuring the boards could withstand the harsh conditions of offshore wind farms. "Our clients love that they can ｄｒｏｐ off a PCB and pick up a fully tested, coated product—no middlemen, no delays," says technical lead Barbara Kovac. "It simplifies their supply chain and reduces the risk of errors."
Founded in 2012, Slovenia Conformal Services (SCS) is a relative newcomer, but it's quickly become a favorite among startups and SMEs thanks to its flexibility and customer-first approach. Unlike larger suppliers that focus solely on mass production, SCS caters to low-volume prototyping, medium runs, and large-scale manufacturing—making them a one-stop shop for businesses at every stage of growth. Whether you need 10 prototype PCBs coated for a trade show demo or 10,000 units for a product launch, their team adjusts their processes to fit your needs.
SCS also prides itself on transparency. They offer detailed quotes that break down costs by material, labor, and any additional services (like masking or rework), so clients never have to guess about hidden fees. "We've worked with enough startups to know that budget predictability is key," says founder Janez Petric. "We don't lock clients into long-term contracts, and we're always happy to tweak our services to fit their timeline or budget." With a focus on education, they also provide free consultations to help clients choose the right coating material for their application—whether it's a flexible silicone for a bendable PCB or a hard acrylic for a rugged industrial device.
When PCBs need to survive extreme environments—think offshore oil rigs, deep-sea sensors, or desert-based solar inverters—Primorska Coating Innovations is the supplier of choice. Founded in 2008 in the coastal region of Primorska, the company specializes in advanced nano-coating technologies that provide superior protection against corrosion, salt spray, and UV radiation. Their proprietary nano-ceramic coating, for example, forms a molecular bond with the PCB surface, creating a barrier that's 50% thinner than traditional coatings but twice as durable.
Primorska works closely with clients in the marine and oil & gas industries, where equipment failure can lead to costly downtime or safety risks. "We once had a client who needed PCBs for a subsea drone that would operate 3,000 meters below sea level," recalls R&D manager Tina Golob. "We developed a custom silicone-nano hybrid coating that could withstand the pressure and cold—something standard coatings just couldn't handle." The company also invests heavily in research, partnering with the University of Primorska to develop next-gen coatings that push the boundaries of what's possible in PCB protection.
With roots dating back to 1995, Central Slovenian Coatings (CSC) is one of the oldest and most established conformal coating suppliers in the country. Based in Celje, a hub for automotive manufacturing, CSC has built its reputation on consistency and scalability, handling large-volume orders for some of Europe's biggest automotive brands. Their ISO 9001 certification and strict quality control processes ensure that every PCB that leaves their facility meets the same high standards—whether it's the first unit or the millionth.
CSC's facility features automated coating lines that can process up to 50,000 PCBs per day, using a combination of spray, dip, and curtain coating techniques to accommodate different board sizes and shapes. They also offer custom masking services for PCBs with sensitive components (like connectors or heat sinks) that need to remain uncoated. "In automotive manufacturing, reliability is everything—one faulty PCB can lead to a recall," says quality manager Goran Jovanovic. "That's why we test every batch and provide full traceability reports, so our clients can sleep easy knowing their products are safe."
High temperatures are the enemy of many PCBs, but Karst Conformal Coatings turns that challenge into an opportunity. Founded in 2015 in the Karst region of Slovenia, the company specializes in silicone-based conformal coatings designed to withstand continuous exposure to temperatures up to 200°C (and intermittent spikes to 260°C). This makes them a top choice for clients building PCBs for industrial ovens, power amplifiers, and LED lighting systems—applications where heat management is critical.
Karst's silicone coatings also offer excellent flexibility, making them ideal for PCBs that undergo thermal expansion or vibration. "We recently worked with a client who was manufacturing PCBs for electric vehicle charging stations," says sales director Nika Zorc. "These stations get extremely hot during fast charging, and standard coatings were cracking under the stress. Our high-temp silicone coating solved the problem, and now we're their go-to supplier." With a focus on niche applications, Karst has become a trusted partner for businesses with specialized needs that larger suppliers can't meet.
For PCBs with tight spaces, delicate components, or complex geometries, precision is non-negotiable. Ptuj Precision Coatings, founded in 2007 in the historic city of Ptuj, has mastered the art of selective conformal coating—using automated robots and laser-guided systems to apply coating only where it's needed, avoiding areas like connectors, heat sinks, or sensors that should remain uncoated. This level of precision reduces material waste and ensures that sensitive components aren't compromised.
Ptuj works primarily with clients in the medical device and robotics industries, where PCBs are often packed with miniaturized components. "A typical medical PCB might have hundreds of tiny sensors and microchips, each with different coating requirements," explains lead engineer Luka Krajnc. "Our selective coating technology allows us to target each area with accuracy down to 0.1mm, ensuring every component gets the protection it needs—no more, no less." The company also offers custom masking solutions for unique PCB designs, ensuring even the most complex boards are coated flawlessly.
