BYK-Gardner Strategically Expands into Autonomous Driving Tech with Acquisition of perisens GmbH

In a move that signals a significant shift in the landscape of automotive quality assurance, BYK-Gardner USA—a subsidiary of the global specialty chemicals powerhouse ALTANA—has officially announced the acquisition of perisens GmbH. The Feldkirchen-based technology firm, a pioneer in the development and manufacture of precision testing equipment for automotive radar sensors and radomes, will be fully integrated into BYK-Gardner’s operations.

This acquisition is more than a mere expansion of product lines; it represents a strategic pivot toward the future of autonomous driving, where the intersection of material science and sensor reliability is becoming the critical path for automotive safety.

The Intersection of Material Science and Radar Accuracy

Modern vehicles are increasingly reliant on a sophisticated suite of sensors to navigate the world. Among these, radar sensors are arguably the most vital, providing the "eyes" for adaptive cruise control, collision avoidance, and autonomous navigation. However, these sensors do not exist in a vacuum; they are typically hidden behind plastic components known as radomes (radar domes).

The challenge lies in the paint. To maintain aesthetic appeal and brand identity, manufacturers coat these plastic components with specialized paint systems. If these coatings are not precisely engineered, they can attenuate—or weaken—radar signals, leading to inaccurate data, system latency, or total sensor failure.

By acquiring perisens, BYK-Gardner is positioning itself at the nexus of this challenge. The integration allows the company to move beyond traditional visual quality control—measuring color, gloss, and appearance—into the realm of electromagnetic transparency.

Chronology of Innovation: From University Spin-off to Industry Standard

The story of perisens is one of academic rigor meeting industrial necessity. Founded in 2009 as a spin-off from the Technical University of Munich, the company was built on a foundation of deep-tech research into high-frequency electromagnetic measurement.

• 2009: perisens GmbH is established in the Munich area, focusing on the emerging need for precise radar transparency testing.
• 2014: After years of R&D, perisens launches its flagship RMS-C and RMS-D product series, marking the company’s entry into global markets.
• 2015–2020: The adoption of radar-assisted safety features accelerates globally. Perisens solidifies its footprint by partnering with leading automotive OEMs, radar sensor suppliers, and major paint manufacturers.
• 2023–2024: Negotiations with the ALTANA group culminate in the decision to join the BYK-Gardner portfolio, providing the scalability needed to meet surging global demand.

This trajectory reflects the rapid maturation of the autonomous vehicle market. What began as a niche laboratory requirement has, in less than a decade, become a mandatory standard for high-volume automotive production lines.

Technical Capabilities: The RMS Product Suite

At the core of the acquisition are the RMS-C and RMS-D series. These systems provide a comprehensive bridge between the laboratory and the factory floor.

Laboratory-Grade Precision

The perisens technology is capable of characterizing the radar transparency of complex, curved plastic parts with extreme accuracy. In the R&D phase, engineers can use these systems to validate the chemical formulation of paints and plastics before they reach the assembly line. This ensures that the material stack-up—the combination of substrate, primer, basecoat, and clearcoat—meets the stringent dB-loss requirements specified by radar sensor manufacturers.

Production-Line Integration

Perhaps the most valuable asset in the acquisition is the ability to deploy this technology directly onto robot-controlled production lines. As automotive assembly becomes increasingly automated, manual spot-checking is no longer feasible. Perisens’ patented measurement cells allow for continuous, real-time quality assurance. If a batch of paint deviates slightly from its specified electromagnetic properties, the system can flag it instantly, preventing defective components from being installed on vehicles.

Official Responses and Corporate Strategy

The leadership teams from both organizations have framed the acquisition as a synergistic alignment of "the visible and the beyond."

Dr. Jörg Hinnerwisch, Division President of BYK, emphasized the technological fit during the announcement. "Perisens’ radar measurement instruments are a perfect complement to BYK-Gardner’s innovative color and gloss measurement instruments," Hinnerwisch stated. "This is state-of-the-art technology with excellent prospects for the future, and we are excited to welcome the team to the BYK family."

Dr. Jörg Krames, Managing Director of BYK-Gardner, echoed this sentiment, highlighting the company’s evolving mission statement. "True to our motto, ‘Measure the visible and beyond,’ the integration of this new measurement technology allows us to offer our existing customers in the automotive and coatings industries another milestone in our product portfolio. Radar measurement will be absolutely indispensable for autonomous driving in the future."

From the perisens side, the move is viewed as a necessary catalyst for growth. Dr. Florian Pfeiffer, Managing Partner of perisens, noted that the transition provides the infrastructure to scale. "The integration of perisens into BYK-Gardner will enable us to further develop our existing testing and measurement instruments even faster, increase brand awareness, and consistently drive innovation forward."

Implications for the Automotive Industry

The acquisition of perisens by BYK-Gardner will likely have several cascading effects on the automotive supply chain:

1. Standardization of Quality Protocols

Currently, testing standards for radomes can vary significantly between different Tier 1 suppliers and OEMs. By bringing perisens into the BYK-Gardner ecosystem, the industry may see a more unified approach to quality control. BYK-Gardner’s existing global infrastructure provides a platform for setting global standards in radar measurement, similar to the standards they have already established for color and gloss.

2. Streamlining the "Color-to-Signal" Workflow

Paint manufacturers, who are already long-standing customers of BYK, now have a single-source partner for both aesthetic and functional testing. A manufacturer can now optimize a paint formulation not only for its finish and durability but also for its radar-transparency performance in a single, cohesive workflow. This will significantly shorten development cycles for new automotive exterior components.

3. Accelerated Development of Autonomous Systems

As vehicles move toward higher levels of autonomy (SAE Levels 3, 4, and 5), the reliance on radar will only increase. With more sensors integrated into bumpers, grilles, and emblems, the "electromagnetic signature" of a vehicle’s exterior becomes a critical safety parameter. By providing the tools to manage this complexity, BYK-Gardner is essentially becoming an enabler of safer autonomous vehicle deployment.

4. Workforce Retention and Knowledge Transfer

One of the most critical aspects of this acquisition is the transfer of the perisens workforce to BYK. This ensures that the deep technical expertise—the "brain trust" behind the patented radar measurement algorithms—remains intact. As these employees transition to the larger BYK-Gardner organization, the cross-pollination of ideas between optical measurement experts and electromagnetic measurement experts is expected to yield the next generation of smart inspection systems.

Future Outlook: A New Paradigm in Automotive Metrology

The automotive industry is in the midst of a radical transformation. The shift toward electrification is well-documented, but the shift toward software-defined, sensor-heavy vehicles is equally profound. In this new era, a vehicle’s exterior is no longer just a shell; it is an active component of the vehicle’s electronic system.

BYK-Gardner’s acquisition of perisens signals that the company is prepared to lead in this new paradigm. By successfully bridging the gap between traditional coating technology and modern sensor electronics, the company is ensuring that it remains a vital partner to automotive manufacturers for decades to come.

As autonomous driving technology matures, the ability to "see" through paint will be as important as the ability to see on the road. With the combined strengths of BYK-Gardner and perisens, the industry now has the tools to ensure that these critical radar sensors perform at peak efficiency, regardless of the aesthetic finish of the vehicle.
