Anti-static industrial flooring

An ESD conductive flooring system can be comprised of layers such as copper tape, conductive primer, a base coat, and a thin topcoat. To conduct electrical charge from the surface to the ground, the originally insulative base coat should be made conductive. Self-leveling ESD floors must meet surface-to-surface or surface-to-ground resistance requirements, complying with IEC 61340-4-1, ASTM F150-06, and ANSI / ESD S20.20 standards.

Added to resin, graphene nanotubes create a stable, permanent electrical pathway from the walking surface to the ground and dissipate electrostatic charge over time regardless of humidity.

Ultralow working dosages of graphene nanotubes allow for wide color flexibility while ensuring a wide range of stable electrical resistivity.

Compared with chopped carbon fiber and conductive mica, the required dosage of which is 5–20 wt.% leading to a higher price, graphene nanotubes make it possible to obtain the required conductivity at much lower working dosages starting from 0.01 wt.%, improving cost efficiency.

Due to the length of chopped carbon fiber (2 mm or longer), the base layer thickness must be at least ~2 mm, which complicates installation and raises costs. Additionally, the fiber’s morphology can potentially create insulating “hot spots.” In contrast, graphene nanotubes can be used with various anti-static flooring systems and thicknesses, ensuring stable, permanent surface-to-ground resistance, ultimately reducing ESD flooring costs.
