Your Guide to Protecting PCBs in Harsh Environments
If you've ever held a circuit board and wondered how it survives the humidity of Solomon Islands' coastal towns or the dust of its inland industrial sites, the answer often lies in a thin, protective layer called conformal coating. This unassuming material acts as a shield, guarding PCBs against moisture, chemicals, and temperature swings—critical for electronics that power everything from fishing equipment to medical devices in this island nation. For businesses and hobbyists alike, finding a reliable conformal coating supplier isn't just about buying a product; it's about partnering with someone who understands the unique challenges of local environments.
Conformal coating isn't a one-size-fits-all solution. From acrylic to silicone, each type offers different levels of flexibility, heat resistance, and durability. And with Solomon Islands' mix of marine salt spray, tropical rains, and industrial pollutants, choosing the right coating (and the right supplier to apply it) can mean the difference between a device that lasts five years and one that fails in six months. That's why we've compiled this list of the top 10 conformal coating suppliers in Solomon Islands—each vetted for quality, reliability, and a customer-first approach.
Nestled in Honiara's industrial district, Solomons PCB Protect has been a cornerstone of the local electronics scene for over a decade. What sets them apart? Their team doesn't just apply conformal coating—they engineer protection plans tailored to your device's specific environment. Whether you're building a sensor for a fishing boat (think saltwater and constant vibration) or a medical monitor for a rural clinic (humidity and dust), they start with a free consultation to recommend the best coating type.
Their specialty? Acrylic conformal coating for cost-effective, general-purpose protection, and silicone-based options for devices that need flexibility (like those in moving parts). They're also one of the few suppliers in Solomon Islands certified to apply UV-curable coatings, which dry in minutes instead of hours—perfect for tight production deadlines. And if you're new to conformal coating, their "Coating 101" workshops (held monthly) teach teams how to apply conformal coating basics, ensuring you can maintain small batches in-house.
Customers rave about their 48-hour turnaround for small orders and commitment to transparency—no hidden fees, just a clear quote upfront. "They walked us through every step," says a local manufacturer of solar charge controllers. "We thought we needed a heavy-duty silicone coating, but they showed us that a standard acrylic would work just as well, saving us 30% on costs."
Located in Gizo, Island Coatings & Electronics prides itself on being the "local expert with global standards." Founded by a team of expat engineers who fell in love with Solomon Islands, they bring international experience to the table—including certifications like ISO 9001 and RoHS compliance—without losing the personal touch of a small business. Their focus is on circuit board conformal coating for industrial and marine applications, where durability is non-negotiable.
What makes them stand out? Their mobile coating unit. For businesses in remote areas like Malaita or Guadalcanal, they'll bring their equipment to your site, saving you the hassle of shipping PCBs back and forth. They also offer a unique "coating health check" service: send in an old PCB, and they'll test its existing coating thickness and integrity, then recommend repairs or reapplication. It's a lifesaver for companies looking to extend the life of legacy equipment.
Their most popular service? A hybrid coating that combines the best of acrylic and urethane—hard enough to resist scratches, yet flexible enough to handle thermal expansion. "We had a client with a mining sensor that kept failing due to dust ingress," says their lead technician. "We switched them to our hybrid coating, and they haven't had a failure in two years."
If speed is your top priority, Pacific Conformal Solutions in Auki is the name to know. Specializing in low-volume, fast-turnaround projects, they've built their reputation on getting coatings applied and PCBs back to clients in as little as 24 hours. How do they do it? A streamlined process, including online quoting (you upload your PCB specs, and they send a quote within 2 hours) and a dedicated team for rush orders.
Don't let the speed fool you—quality isn't compromised. They use automated spray systems for uniform coverage (no drips or thin spots) and test every batch with a humidity chamber to ensure protection. Their coating options include parylene, a high-performance polymer that's thinner than a human hair but offers exceptional chemical resistance—ideal for electronics used in agricultural settings, where pesticides and fertilizers can corrode unprotected boards.
For hobbyists and startups, they also offer a "proto-coat" service: small-batch coating for prototypes at a discounted rate. "We remember what it's like to be a small business," says their owner. "We want to help you get your product off the ground without breaking the bank."
Based in Honiara, Solomon Tech Coatings is all about sustainability. They were the first conformal coating supplier in Solomon Islands to achieve carbon-neutral certification, using eco-friendly solvents and energy-efficient curing ovens. But their green focus doesn't stop there—they also offer a recycling program for used coating materials and donate a portion of profits to local marine conservation efforts (fitting, given how many of their clients serve the fishing industry).
Their technical expertise is equally impressive. They specialize in conformal coating for high-voltage PCBs, such as those used in solar inverters and power distribution systems. Their team includes a materials scientist who can custom-formulate coatings for unique challenges—like a recent project for a hydroelectric plant that needed resistance to both water and mineral deposits.
Customers love their "lifetime warranty" on coating adhesion. "If a board coated by us fails due to delamination within five years, we'll recoat it for free," their warranty states. It's a bold promise, but one they've rarely had to honor—thanks to their rigorous pre-coating cleaning process, which removes every trace of flux and oil before application.
As the name suggests, Coastal Circuit Shield in Noro is all about protecting electronics from the harsh realities of island life—specifically, saltwater corrosion. Their team has worked with everyone from yacht builders to coastal weather stations, developing a reputation for coatings that stand up to constant salt spray. Their secret? A two-step process: first, a primer that bonds to the PCB, then a thick layer of fluoropolymer coating that repels water and chemicals.
They also offer on-site training for clients who want to handle coating in-house. Their "How to Apply Conformal Coating" workshops cover everything from surface preparation to spray technique, with hands-on practice using their equipment. "We don't just want to be your supplier—we want to be your partner," says their training coordinator. "If your team can apply the coating correctly, you'll save time and money in the long run."
For clients with large orders, they offer bulk discounts and dedicated account managers. One fishing gear manufacturer notes, "We coat hundreds of PCBs a month for our fish finders. Coastal Circuit Shield assigned us a rep who knows our specs by heart—no more repeating ourselves every time we place an order."
Green Island Coatings, located in Kirakira, is a family-owned business that's been serving the Eastern Solomon Islands for over 15 years. What makes them special? Their commitment to accessibility. They offer free delivery to remote islands (via local boat services) and flexible payment plans for small businesses. "We know cash flow can be tight for startups," says the owner. "We're happy to work with you to get your PCBs protected when you need it."
Their coating portfolio is focused on versatility, with options for everything from consumer electronics (like smart home devices) to rugged industrial sensors. They're particularly known for their acrylic conformal coating, which offers a great balance of cost and protection for most applications. For clients needing something more heavy-duty, they also stock silicone coatings that can withstand temperatures from -50°C to 200°C—perfect for equipment used in cold storage or near engines.
Word of mouth has made them a favorite among local schools and community projects. "We helped a group of students coat PCBs for a solar-powered water purification system," the owner recalls. "Seeing that project change lives in a rural village? That's why we do this."
Solomon Industrial Coatings in Tulagi is the go-to for large-scale manufacturing. With a production line that can handle up to 5,000 PCBs per day, they're equipped to take on mass orders for clients in sectors like telecommunications and energy. Their facility includes automated conveyor systems and quality control checkpoints at every stage, ensuring consistent coating thickness and coverage.
They're also leaders in innovation, recently introducing a nanotechnology-based conformal coating that repels water and dust at a molecular level.

"We've worked with companies in Australia and New Zealand," says their export manager. "They trust us to deliver coatings that meet their strict quality requirements, and we're proud to represent Solomon Islands on the global stage."
Coral Coast Conformal, based in Henderson, is all about precision. Their team uses advanced optical inspection systems to ensure every square millimeter of a PCB is coated evenly—no missed spots, no bubbles. This attention to detail makes them a top choice for medical device manufacturers, where even a tiny uncoated area could lead to device failure (and potential harm to patients).
They specialize in parylene coating, a vapor-deposited polymer that creates an ultra-thin, pinhole-free barrier. While more expensive than acrylic or silicone, parylene is ideal for sensitive electronics like pacemakers or hearing aids, where thickness and weight matter. "We once coated a PCB smaller than a postage stamp for a research lab," their lead engineer says. "The precision required was intense, but seeing the final product work perfectly? That's the reward."
They also offer validation services, providing detailed reports on coating thickness, adhesion, and resistance to environmental factors. For clients in regulated industries, this documentation is critical for compliance—and Coral Coast Conformal makes sure it's always thorough and easy to understand.
Serving the Bougainville region, North Solomon Coatings is a relative newcomer but has quickly made a name for itself with its customer service. Their tagline—"We answer the phone, and we deliver on time"—might sound simple, but in an industry where delays can derail projects, it's a game-changer. They offer 24/7 support for emergency orders and even provide a tracking link so you can see exactly when your PCBs will be ready.
Their coating options are tailored to the region's unique needs, with a focus on protecting against volcanic ash (a common issue in parts of Bougainville) and high humidity. They recommend their urethane conformal coating for these conditions, as it forms a hard, chemical-resistant barrier that's easy to clean. For clients on a budget, they also offer a budget-friendly acrylic option with a shorter warranty but solid protection for less critical applications.
Local miners and agricultural businesses are among their biggest fans. "When your equipment is in the field, you can't afford downtime," says a farm equipment dealer. "North Solomon Coatings gets that—they once rushed a batch of coated PCBs to us in 12 hours when our main supplier fell through. We'll never go anywhere else."
Rounding out our list is Islandwide PCB Services, a Honiara-based supplier that lives up to its name by offering coverage across the entire country. With satellite offices in Gizo, Auki, and Kirakira, they make it easy for clients in remote areas to access quality conformal coating without the hassle of long-distance shipping. Their mobile teams can even set up temporary coating stations at your facility for large projects.
What really sets them apart is their "one-stop shop" approach. In addition to conformal coating, they offer PCB design consultation, component sourcing, and assembly services. For businesses that want to outsource the entire process, this integration saves time and reduces the risk of miscommunication between suppliers. "We had a client who came to us with just a schematic," says their project manager. "We designed the PCB, sourced the components, assembled it, coated it, and delivered the finished product—all in six weeks. That's the power of integration."
