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?

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.

Unlike other additives, TUBALL™ graphene nanotubes deliver good performance of all key parameters of textile. Effective at ultralow doses, nanotubes provide anti-static performance without affecting a fabric’s mechanical properties, color, or production processes. Unlike carbon black, they produce no dust and leave no carbon on the surface, while minimally impacting formulation viscosity and density.
