If you've ever held a sleek electronic device—a smartphone, a medical monitor, or even a car's control module—and wondered how its internal components stay protected from moisture, dust, or temperature swings, you've stumbled upon the magic of PCBA low pressure injection coating. This specialized process involves encapsulating printed circuit board assemblies (PCBA) with a thin, durable layer of polymer, creating a shield that safeguards delicate electronics without adding bulk. For businesses in Argentina and beyond, finding a reliable supplier for this critical service isn't just about ticking a box—it's about ensuring product longevity, compliance with global standards, and ultimately, building trust with customers.
Argentina's electronics manufacturing sector has been quietly thriving, with local suppliers increasingly gaining recognition for their technical expertise, adherence to international quality norms, and flexibility in meeting diverse client needs. Whether you're a startup developing a prototype or a multinational scaling mass production, the right PCBA low pressure injection coating partner can make or break your project. In this article, we'll walk you through the top 10 suppliers in Argentina, breaking down what makes each stand out, so you can find the perfect fit for your next project.
Let's be honest: in electronics manufacturing, cutting corners on protective coatings can lead to costly disasters. A poorly applied coating might crack under thermal stress, let moisture seep in, or interfere with the PCB's functionality—all of which can result in product failures, recalls, or damaged reputations. That's why partnering with a supplier who understands the nuances of low pressure injection coating is non-negotiable.
But it's not just about protection. Today's clients demand more: compliance with regulations like RoHS, quick turnaround times to stay ahead of market trends, scalability from small batches to mass production, and transparent communication. The best suppliers don't just apply coatings—they act as partners, offering technical support, material expertise, and tailored solutions that align with your project's unique goals.
Founded in 2005 in Buenos Aires, TechShield Coatings has grown from a small local workshop to one of Argentina's most trusted names in PCBA protection. What sets them apart? A relentless focus on innovation. They were one of the first suppliers in the country to adopt automated low pressure injection molding systems, reducing human error and ensuring consistent coating thickness across every board.
Their service portfolio covers everything from prototype coating for startups to high-volume production runs for automotive and industrial clients. Clients rave about their "one-stop shop" approach: not only do they handle coating, but they also offer pre-coating cleaning, post-coating testing, and even help with material selection based on your device's operating environment (think extreme temperatures or high humidity). With ISO 9001 and RoHS certifications under their belt, TechShield is a go-to for businesses prioritizing quality and compliance.
"We don't just coat boards—we solve problems," says Maria Gonzalez, their technical director. "Last year, a client came to us with a medical device that kept failing due to moisture ingress. We adjusted the coating material and application parameters, and now their product has a 99.7% reliability rate in the field."
Based in Cordoba, ElectronGuard Solutions has carved a niche for itself by specializing in low pressure coating for medical and aerospace electronics —industries where failure is simply not an option. Founded by a team of ex-aerospace engineers, they bring a military-grade precision to every project.

Instead of relying on off-the-shelf polymers, ElectronGuard works with clients to develop custom coating formulas tailored to specific threats, like chemical exposure or vibration resistance. They're also pioneers in "green" coating solutions, using eco-friendly polymers that meet both RoHS and REACH standards without compromising durability.
Small to medium businesses (SMBs) love their flexibility. Unlike some larger suppliers that require minimum order quantities, ElectronGuard happily takes on low-volume projects, making them ideal for startups or companies testing new product lines. Their lead times are impressive too—most prototype orders ship within 3–5 business days, and mass production runs are typically completed in under two weeks.
With a factory in Rosario, SouthCoat Industries prides itself on being a "global-local" supplier. While their roots are in Argentina, they've built strong partnerships with material suppliers in Europe and Asia, giving clients access to cutting-edge polymers that might not yet be available locally. This global reach also extends to their client base—they regularly work with international companies outsourcing production to Argentina for cost savings without sacrificing quality.
Their claim to fame? Fast delivery low pressure molding PCBA assembly . Using a combination of lean manufacturing practices and 24/7 production shifts for urgent orders, they've earned a reputation for meeting tight deadlines. "We once turned around a 5,000-unit order for a European automotive client in 10 days," says Juan Fernandez, their operations manager. "They thought we were bluffing until the shipment arrived on their doorstep."
SouthCoat also stands out for their commitment to sustainability. Their facility runs on 30% solar power, and they've implemented a zero-waste policy for coating materials, recycling excess polymer into custom blends for less critical applications. For eco-conscious brands, this is a major plus.
PCM, located in Mendoza, is all about specialization. Unlike suppliers that cater to every industry, they've doubled down on industrial and agricultural electronics —think sensors for farm equipment, control systems for manufacturing lines, and ruggedized panels for mining machinery. This focus has let them master the unique challenges of these sectors: coatings that resist oil, dirt, and mechanical shock.
Their secret weapon? A state-of-the-art testing lab where they simulate real-world conditions. Before shipping a single coated board, they subject samples to temperature cycling (-40°C to 125°C), humidity testing (95% RH for 1,000 hours), and even mechanical stress tests to ensure the coating holds up. "Our clients work in harsh environments," explains Laura Martinez, their quality assurance lead. "We need to be sure our coatings can keep up."
PCM also offers a rare service: coating repair. If a board gets damaged during assembly, they can strip the old coating, repair the component, and re-coat it—saving clients from scrapping entire batches. For businesses working with high-value components, this can translate to significant cost savings.
A relative newcomer (founded in 2018), Innovatech has quickly made a name for itself by targeting the consumer electronics market . Based in La Plata, they specialize in coatings for wearables, smart home devices, and small appliances—products where aesthetics matter as much as protection. Their coatings are not only durable but also ultra-thin and clear, preserving the board's visual design for devices where internal components are on display.
What's their trick? They use nano-polymer blends that flow smoothly around even the tiniest components (down to 01005-sized resistors), ensuring no air bubbles or gaps. This precision has made them a favorite among startups designing compact, high-density PCBs. "We had a client with a fitness tracker that kept shorting out because moisture was getting into the battery compartment," says CEO Carlos Mendez. "Our ultra-thin coating sealed the gaps without adding bulk, and now their product has a 12-month warranty instead of 6."
Innovatech also offers competitive pricing for low-volume orders, making them a hit with crowdfunding campaigns and small-batch product launches. They even provide free sample coatings for prototypes—letting clients test the quality before committing to a full order.
As the name suggests, SecureCoat, based in San Miguel de Tucumán, prioritizes security—specifically, electronics for defense and government applications . This niche requires more than just great coatings; it demands strict confidentiality, traceability, and compliance with military standards like MIL-STD-810H.
Every step of their process is documented, from material receipt (with batch testing and certificates of compliance) to coating application (with detailed logs of temperature, pressure, and cycle times). They even assign a dedicated project manager to government clients, ensuring clear communication and adherence to strict procurement timelines. "In our line of work, trust is everything," says Diego Alvarez, their government contracts director. "We can't afford to cut corners on documentation or security."
SecureCoat also offers specialized coatings for EMI/RFI shielding, combining physical protection with electromagnetic interference resistance. For devices like communication radios or radar systems, this dual functionality is a game-changer.

Their facility is also zero-waste certified, with all packaging and excess materials either recycled or repurposed.
But don't let the "green" label fool you—their coatings are tough. They've developed a water-based polyurethane blend that offers the same protection as traditional solvent-based coatings but with 90% fewer volatile organic compounds (VOCs). "We proved to clients that sustainability doesn't mean sacrificing performance," says Sofia Lopez, their founder. "Our coatings meet the same IPC standards as any other supplier, but with a fraction of the environmental impact."
GreenShield also offers carbon footprint reporting for each order, helping clients track and reduce their own environmental impact. For brands looking to market their products as eco-conscious, this data is invaluable.
Speed is the name of the game at RapidCoat, a Buenos Aires-based supplier that caters to startups and prototype developers . They understand that in the fast-paced world of tech, getting a product to market first can mean the difference between success and obscurity. That's why they've optimized their process for rapid turnaround: prototype coatings in as little as 24 hours, and small-batch production (up to 500 units) in 3–5 days.
How do they do it? A streamlined workflow with dedicated prototype lines that run separately from mass production, and a team of technicians on call 24/7 for urgent orders. "We once had a startup client who needed 100 coated boards for a trade show in 48 hours," recalls Martin Torres, their prototype division head. "We pulled an all-nighter, and they had their samples ready to demo."
RapidCoat also offers design consultation. Their engineers will review your PCB layout before coating, suggesting tweaks to improve coating coverage (like adding relief holes or adjusting component spacing). For first-time designers, this guidance can save time and prevent costly rework.
As part of the international GlobalCoat Group (with facilities in Brazil, Chile, and Spain), this supplier brings global resources to local clients. Their Buenos Aires facility is a mirror of their European counterparts, using the same equipment, materials, and processes—ensuring consistency for clients with multi-country production needs.
