Features of DENATRON

DENATRON is a conductive coating material of Type-P, developed based on a polythiophene-based conductive polymer named PEDOT:PSS, and Type-C, developed based on carbon nanotubes CNT.
As PEDOT:PSS has an extremely high conductivity and works in the form of a thin film, it is almost invisible when the film is formed. When the conductivity is adjusted, DENATRON can be used in a wide range of applications, including antistatic layers (layers to prevent the accumulation of static electricity), transparent electrodes, and biomedical electrodes.

It can be applied as a coating in general wet processes and heat-treated at a relatively low temperature to form a coating film.

DENATRON is a water- or water/alcohol-based conductive coating that mitigates environmental burdens.

What is PEDOT:PSS?

PEDOT:PSS is a kind of conductive polymer, and its name is an abbreviation for the names of a complex substance consisting of poly (3,4-ethylenedioxythiophene) (PEDOT) and poly- styrene sulfonic acid (PSS).

PEDOT:PSS is superior in stability, transparency, and film-forming properties compared to other conductive polymers.

Mechanism of Conduction

Bipolarons (dications) that are generated by PSS extracting electrons from PEDOT move inside molecules and also hop among molecules, so that electricity can flow.

Highly hydrophilic PSS acts as a dispersant and stably disperses PEDOT in water by keeping the PEDOT in the form of multi-molecular gel particles ranging from about 10 to 200 nm in size.

Mechanism of Conduction

What is Nano Carbon?

There are various types of Nano Carbon such as Fullerene, Graphene, and Nanotubes. Unlike PEDOT, Type-C is produced by using special dispersants and special dispersing machine.
The dispersed nano-sized particles bring its highly transparent.
In addition, it has the excellent weather resistance due to its C-C bonds.

The Top Reliable Brand

Conductive polymers are now widely known as a Nobel Prize-winning technology.
We started to develop coating agents using conductive polymers ahead of all other companies in the world 20 years ago and established our own advanced formulation technology. Their first application was antistatic coatings for optical films. These gained a good reputation as transparent antistatic layers for optical films that had suffered from trouble with dust in the manufacturing process, which made the start of our business successful.

We are now expanding our business activities in the field of transparent electrode applications, in addition to antistatic applications. By continuously accumulating know-how in development, manufacturing, and quality control, we will continue to move forward as the most reliable supplier for our customers.

Our focus on product development

Creating coating materials specialized for X.

It goes without saying, but the performance required of materials varies depending on the application. For example, should the performance required of DENATRON, as a conductive polymer coating material, be focused on conductivity, transparency, cost, or all of these? It significantly varies depending on the customer and the customers of customers. Even if the required performance specifications are fulfilled, they have no meaning unless it works well in the customer’s environment.

Not only conductive coating materials

Nagase ChemteX not only develops conductive coating materials, but also actively develops coating materials related to conductive materials and functional coating materials. Therefore, we can suggest a total solution as well. Adding a UV protective overcoating agent to DENATRON substantially improves weather resistance.

Wide views and deep thoughts

Although we mainly develop formulation techniques with PEDOT:PSS, we also develop mixed raw materials and additives themselves, pursuing not only formulations but also more opportunities. Besides, we value our connections with research institutes including universities, raw material manufacturers, and analysis equipment manufacturers.

Even if we face difficult issues such as trade-offs, we will go back to the mechanism of the product and repeatedly reconsider in order to discover the essence of the product to find an answer.

We‘ll do our best to solve any challenging requests, so please feel free to ask us about anything, including problems in adding conductivity and so on.
