Graphene nanotubes for powder
coatings: electrical conductivity,
durability, and aesthetics
TUBALL™ graphene nanotubes enhance powder coatings by providing stable anti-static properties while preserving the original mechanical properties of the material. Nanotubes enable the creation of colorful, durable coatings with ESD protection, using standard production technology without the need for special adaptations. By adopting graphene nanotube-enhanced electrically conductive powder coatings, manufacturers can overcome the limitations of conventional conductive agents. This results in a cleaner production process with no carbon dust, greater flexibility in final formulations, and improved overall cost-efficiency.

Anti-static powder coatings
What are ESD powder coatings?
Electrostatic dissipative coatings are designed to prevent the buildup of static electricity on surfaces. Compared to liquid coatings, powder coatings can be effectively applied to both vertical and horizontal surfaces. They also offer greater efficiency, enhanced mechanical strength, improved durability, and increased environmental friendliness, as they are practically solvent-free.
ESD powder coatings are widely used in industries where electrostatic discharge can damage sensitive electronic components, such as in electronics manufacturing, cleanrooms, automotive, and aerospace applications.
These ESD coatings must provide a permanent, stable level of electrical conductivity independent of humidity, to safely dissipate static charges and protect equipment and personnel. TUBALL™ graphene nanotubes provide epoxy coatings and polyester coatings with ESD protection while maintaining color and resistance to wear, corrosion, and chemicals. Such ESD powder coatings can be applied via spray, ensuring easy processing and cost-efficiency.
Graphene nanotubes outperform standard additives
TUBALL™ graphene nanotubes provide conductivity in powder coatings, offering a powerful alternative to carbon black, anti-static liquid agents, and conductive mica. These ultra-strong, electrically conductive, flexible nanotubes are effective at ultralow dosages—dozens of times lower than conventional additives—delivering unmatched performance. The result is superior electrostatic dissipative, durable, high-performance coatings with lighter colors and maintained mechanical properties over time.

Permanent, stable conductivity
From 0.01 wt.%, TUBALL™ graphene nanotubes in epoxy or polyester forms a conductive 3D network, enabling a full range of electrical resistivity from 10⁴ to 10⁹ Ω/sq, safeguarding people and devices from electrostatic charge.
Maintained mechanical performance
In contrast to conventional conductive additives, the ultralow dosage of TUBALL™ nanotubes required and nanotubes’ unique morphology help preserve key mechanical properties such as adhesion, impact resistance, and crack resistance.
Variety of color
TUBALL™ nanotubes enable the production of light-colored or bright coatings with stable ESD performance. Their ultralow working dosages ensures both aesthetics and conductivity. With a high aspect ratio, these nanotubes form a conductive network at minimal concentrations, allowing precise control over color and finish.
