We are inspired to continue to develop surface treatment technology to make breakthroughs in the future. Our portfolio of advanced technologies includes
Plasma Enhanced Chemical Vapor Deposition (PECVD)
At Plasmalex, we specialize in advanced PECVD technologies that enhance surface properties, improve material performance, and create highly functional coatings that meet specific industrial needs.
PECVD technology is used to achieve higher-quality coatings in the electronics, automotive, and aerospace industries. This process allows for procedures to be executed in a controlled manner producing quality, uniform thin coatings that increase the efficacy and durability of parts. The biggest advantages of this technology are improved performance, low-temperature deposition, and highly controlled film properties.
Atmospheric PECVD
Atmospheric PECVD is a modification of the standard PECVD process. The atmospheric PECVD solutions from Plasmalex provide diverse and high-performance depositing for multiple industries.
It enables us to provide benefits of both plasma-enhanced deposition with the convenience of working at atmospheric pressure, enabling the deposition of high-quality thin films for a wide range of industrial applications. It is cost-effective and scalable, increases energy efficiency, and is sustainable for the environment.
Biocompatible Coatings
Plasmalex offers advanced biocompatible coating solutions that enhance the performance, longevity, and safety of medical devices used in implants, diagnostics, and therapeutic applications.
We provide bio-compatible coatings for various medical applications and implantation. These coatings are intended to produce protective and durable structures that provide a high quality and safe performance inside the human body.
What is Plasma?
Plasma is considered the fourth state of matter after solid, liquid and gas. By adding energy matter can be transformed from solid to liquid, from liquid to gas and from gas to plasma.
At the plasma stage matter exists in the form of a gas of ions and free electrons and is highly electrically conductive. Although plasma is abundant in the universe, natural occurrences are relatively rare on earth. Lightning, static electricity and auroras are the primary sources of natural plasma.

Plasma can be generated in different ways. CPI, specializes in atmospheric plasma. Europlasma is specialized in low pressure (vacuum) plasma
Benefits of plasma technology for surface treatment
Plasma technology for surface treatment solutions offers several benefits:
- High precision surface cleaning, activation and etching.
- Very consistent nanocoating quality
- The process penetrates in the molecular level of material.
- A low process temperature, important for sensitive substrates and material handling
- Low chemistry consumption
- Environmentally friendly production process
Low environmental footprint
- Compared to conventional chemical coatings Plasmalex’ processes guarantee the lowest environmental footprint
- The lately developed PlasmaGuard® coating chemistry is halogen free.
- Moreover, thanks to their high filtration system, Plasmalex machines are safe in use.

Plasmalex has the most advanced technology in the world for industrial size roll-to-roll atmospheric plasma applications:
- We have a patented electrode/gas diffusor assembly which ensures:
- Control of the chemistry
- A homogeneous ultra-thin coating (1-10 nm) of over 2 m width
- Reduced electrode fouling
- No contamination of the product by plasma generated powders

Industrialized atmospheric plasma applications come with some challenges that we overcome
- Inerting (O2and H2O)
- Gas and monomers handling
- Power management
- To avoid the risk of poor coating quality
- Process industrialization over width and length
- Homogeneity over wide width and length
Therefore we have an important focus on R&D with:
- Continuous Research on the interaction of the different process parameters
- There are up to 89 interconnected plasma parameters to control (classically 20-40)
- We have a continuous process to control the results so that a stable treatment quality is guaranteed
- Continuous Research on various generator technology.
- We continuously test different technologies to select the optimal technology for each application
- We focus on chemistry in the plasma as a sustainable answer to the traditional wet chemistry solutions
