Graphene nanotubes for automotive primers: conductivity, cost benefits and preserved light colors

TUBALL™ graphene nanotubes are applied via easy-to-use TUBALL™ MATRIX, which is a line of additives based on polymer carriers and pre-dispersed TUBALL™ graphene nanotubes.

Choose the TUBALL™ MATRIX product based on the carrier medium that suits your formulation:

Target system

Solvent-based acrylic systems

Water-based acrylic systems

Additive carrier

Plasticizer + stabilizing agent

Surfactant + stabilizing agent

Triethylene glycol dimethacrylate + ammonium salt of polyolefin-based derivatives

Alkylene glycol derivative + distyryl biphenyl derivative


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.
