How anti-static flooring works

Any accumulated electrical charges should be conducted from the surface to ground.
Requirements example
Surface-to-ground resistance:
- dissipative range: 109–106 Ω
- conductive range: 106–2.5⋅104 Ω
According to ASTM F150. Some flooring systems can also include an additional thin topcoat.
TUBALL™ graphene nanotubes are a versatile conductive agent offering strong performance on all key parameters

Note: this diagram provides average trends compared with other additives, based on OCSiAl data. Product performance may vary depending on product type and formulation.
Low working dosages and flexibility in basecoat thickness
Comparing with chopped carbon fiber and conductive mica, TUBALL™ nanotubes allow the required conductivity to be obtained at much lower working dosages.

Surface-to-ground resistance at different base coat thickness

Because of the length of chopped carbon fiber (2 mm or longer), the thickness of the base layer must be at least as much (~2 mm). This can result in difficulties in the installation process, increased costs, and the possibility of there being insulating “hot spots”. In contrast, TUBALL™ can be used with various anti-static flooring systems and thicknesses.
Conductive mica has the highest price per property, which is a result of the initial high price of this ESD additive combined with the high working dosage required, which is ~ 5–20 wt.%.
Product performance may vary depending on product type and formulation.
Full range of electrical resistivity while preserving color

Results for epoxy resin D.E.R. 351. Samples include 5 wt.% of TiO2 as a whitening agent. ASTM D257
Easy to apply
TUBALL™ MATRIX can be processed with standard equipment that is widely used in the coatings industry.
Standard single-shaft high-speed mixer

25 min total dilution time

Instant quality control with a grindometer to reach particle size ≤ 15 µm

Other benefits provided by TUBALL™ nanotubes for static dissipative flooring:
- Floors with TUBALL™ nanotubes can be used without conductive primer
- Low dosage gives greater flexibility in the final formulation
- Easy to apply and the low dosage makes the logistics less complex and more efficient
