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.
Сolor opportunities
TUBALL™ nanotubes, applied at low dosages, allow the production of colorful and even light gray primers with an L-value as high as 75%.

Cost performance
In contrast to other conductive additives used for light-colored primers (e.g. conductive TiO2 or mica), TUBALL™ nanotubes can be applied at low dosages, providing cost efficiency.
Standard basecoat thickness regardless of color
The light colors of primers containing TUBALL™ nanotubes provide the opportunity to apply a thinner basecoat in comparison with primers containing other carbon conductive agents.

Standard processing
TUBALL™ MATRIX can be applied with widely used equipment.

Other benefits provided by TUBALL™ nanotubes for conductive primers:
- Clean production without carbon dust
- Low dosage gives greater flexibility in the final formulation
- Easy to apply and the low dosage makes the logistics less complex and more efficient.
