Solutions for Slot-Die Coating Under an Inert Gas Atmosphere

Slot-Die Coating Under a Controlled Atmosphere

MBRAUN enables slot-die coating under ultra-pure inert gas conditions in the ppm range, providing ideal conditions for demanding coating processes. Our glovebox systems ensure a permanently stable and precisely controlled atmosphere, allowing even highly sensitive materials to be processed reliably. The result is maximum process reliability, consistently high quality, and reproducible results—even for complex and solvent-based applications.

Processing of highly sensitive materials under optimum conditions
Effective protection against oxidation and moisture absorption
Maximum reproducibility through a stable process environment
Safe handling of solvent-based processes

For highly demanding coating applications, our laminar flow solutions provide an additional advantage by creating an almost particle-free environment, minimizing the risk of contamination and ensuring even greater process reliability.

MBRAUN as Your System Integrator for Slot-Die Coating

A key advantage of slot-die coating is its ability to produce highly precise thin films with excellent reproducibility while offering cost-effective process scalability. MBRAUN leverages this potential by developing customized system solutions tailored precisely to your requirements.

Our glovebox systems enable the seamless integration of sheet-to-sheet (S2S) equipment, conventional roll coaters, and continuous roll-to-roll (R2R) processes, creating a continuous process chain from laboratory research to pilot and pre-production manufacturing under a consistently controlled atmosphere.

Working closely with an established network of specialized technology partners, we act as your single-source system integrator. From selecting the appropriate components to delivering a fully operational turnkey solution, you receive everything from one source - efficiently integrated, perfectly coordinated, and designed for future scalability.

Our Scope of Services:

Selection and specification of suitable slot-die coating systems
Mechanical integration into new or existing gloveboxes
Planning and implementation of media supply and process interfaces
Development of comprehensive safety concepts
Centralized project coordination and implementation

The result is a powerful, fully integrated solution that optimally supports your specific processes under a controlled atmosphere while ensuring maximum efficiency and scalability.

Slot-die coating is a highly precise coating process for the rapid deposition of thin, homogeneous films with minimal material loss. The coating material is applied uniformly through a precisely engineered slot die onto a moving substrate.

Compared to other coating methods, slot-die coating provides precise control over film thickness, material deposition, and process parameters while offering excellent scalability from laboratory research to pilot and pre-production manufacturing. It also supports a variety of process architectures, including sheet-to-sheet (S2S), roll coater, and continuous roll-to-roll (R2R) coating.

During slot-die coating, the process liquid is precisely metered and applied to the substrate through a precisely engineered slot die at a controlled flow rate. The coating head moves relative to the substrate, or alternatively, the substrate is transported beneath the coating head.

This precisely controlled dispensing principle produces uniform thin films with excellent reproducibility and outstanding material efficiency.

Slot-die coating combines precision, efficiency, and industrial scalability, making it one of the key technologies for modern high-performance coatings. The technology is used to coat substrates such as glass, metal, polymer films, and both flexible and rigid materials.

As a result, slot-die coating is ideally suited for applications in battery technology, perovskite and thin-film photovoltaics, printed electronics, and functional coatings.
