Coatings
Precise, uniform coatings for diverse applications
Coatings are applied to assembly parts to create protective layers that ensure long-term reliability and safety. These coatings serve multiple purposes: preventing corrosion on mechanical joints and exposed surfaces, reducing fire hazards with fire-resistant materials – such as on battery covers in EV battery production – and blocking moisture ingress to maintain battery integrity and performance. Advanced coating technologies enable precise application with uniform thickness, clean edges, and minimal material waste, delivering high process reliability while supporting cost efficiency.
Types of safety & sound coatings
From fire‑resistant coatings that enhance safety, to dielectric layers that prevent electrical failures, to precise conformal coatings that guard sensitive electronics, and sound‑dampening materials that reduce noise levels, our solutions help extend equipment life and ensure reliable operation. Explore the different types of safety and sound coatings that keep your systems secure, efficient, and compliant with industry standards.
Fire protection
Fire protection coatings are essential for EV battery safety, helping delay fire spread during thermal runaway and preventing battery cover burn-through in the rare event of cell ignition.
The main challenge lies in achieving a uniform layer with precise coverage while avoiding overspray, which can lead to material waste and additional masking steps.
Solution and key features:
To overcome these challenges, a flat stream application of 2K materials with our FlexS.Seal applicator is used. This method ensures consistent thickness and clean edges without overspray. By eliminating masking and reducing material waste, the process improves safety, minimizes health risks, and delivers high process reliability.
Dielectric coating
Dielectric coating improves battery safety and performance by providing electrical insulation, preventing short circuits, and protecting against moisture, salt, acids, and corrosion.
Solution and key features:
It can be applied via PET film or sprayed directly, with attention to challenges like sharp edges, overspray, and precise thickness control. These are effectively addressed by using a flat stream application with our FlexS.Seal applicator.
Conformal coating
With conformal coating, a protective layer is applied to the surface of the PCB to safeguard components and circuits from external influences such as moisture, chemicals, dust, vibration, shock, and other mechanical stresses. In addition to environmental protection, these coatings provide electrical insulation that reduces the risk of leakage currents and short circuits, helping to prevent overheating, fire hazards, and component failure.
The system continuously monitors voltage and current, instantly interrupting the circuit when a fault is detected. Together, these protective functions significantly extend the lifespan of the PCB and enhance overall reliability.

Sound dampening
Sound dampening coatings are applied inside the vehicle to reduce vibrations and noise, creating a quieter and more comfortable cabin. These coatings work by sealing joints and surfaces, absorbing vibrational energy, and preventing resonance. The result is improved acoustic performance and enhanced driving comfort.
Solution and key features:
An efficient and flexible way to apply liquid sound‑dampening material is with a flat stream application, a low‑pressure method commonly used for LASD. The material can be placed precisely where needed and in exactly the right quantity –more material in high‑vibration hotspots and less in low‑vibration areas – supporting optimal performance and weight reduction.
Types of corrosion and moisture protection coatings
From specialized coatings that protect exposed screws, joints, and edges against rust to durable underbody coatings that shield components from moisture, salt, and abrasion, each solution is engineered to prevent corrosion and extend equipment life. Explore the different types of protective coatings designed to keep your systems resilient, reliable, and long‑lasting.
Protection of blank screws, joints & edges
Corrosion protection coatings are essential for safeguarding exposed metal areas such as blank screws, joints and edges. These uncoated fastening points are particulary vulnerable and require precise and reliable coverage to ensure long-term durability and performance.
Solution and key features:
To achieve this, dynamic drop application technology (IDDA.Seal) is used, enabling pinpoint accuracy in material placement. This method allows individual droplet control, which not only guarantees exact coverage but also minimizes material consumption. The result is a highly efficient process that combines precision with flexibility.
Additionally, the system is designed for easy serviceability, making maintenance straightforward and cost-effective. By leveraging advanced dispensing solutions, corrosion protection coatings deliver superior reliability while optimizing resources and performance.
Underbody protection
Moisture protection coatings prevent harmful gas evaporation and block humidity ingress, which is critical for battery safety and performance. The challenge lies in applying these materials accurately on complex geometries while maintaining flexibility in application distance.
As part of these moisture protection solutions, underbody protection plays a key role. It applies a protective coating to the vehicle’s underside to guard against stone chips, road debris, moisture, and corrosion. This durable layer absorbs impacts and prevents damage to metal surfaces, helping extend the vehicle's lifespan and improve overall safety.
Solution and key features:
Advanced dispensing technologies use bead or swirl application with systems like our E-Swirl applicator. This approach ensures precise material placement, even on intricate surfaces, and integrates vision systems for real-time quality control.
Key features include flexible application distances, high accuracy, and optimized material use - delivering reliability. For underbody protection, these spray‑based systems enable uniform coverage and long‑term resistance, ensuring consistent coating performance even under harsh operating conditions
