Graphene nanotubes
conductive agent for lining coatings 

TUBALL graphene nanotubes add electrical conductivity to lining coatings, while preserving mechanical properties and allowing light colors to facilitate visual inspections.

TUBALL GRAPHENE NANOTUBES ARE A VERSATILE CONDUCTIVE AGENT OFFERING STRONG PERFORMANCE IN ALL KEY PARAMETERS

 Preserved light colors 

The use of TUBALL graphene nanotubes conductive filler provides a full range of electrical resistivity of 10⁸–10⁴ Ω·cm, while allowing for a wide range of light colors to meet customer requirements, including facilitating visual inspections and more efficient servicing.

 Maintained mechanical properties

TUBALL nanotubes, in contrast to traditional conductive agents, maintain the mechanical properties of the original non-conductive epoxy coating, resulting in a high level of durability and a prolonged service life.

Preserved adhesion	Maintained impact resistance	Maintained resistance to cracking
ISO 2409. No detachment of coating from substrate after cross-cut adhesion test	ISO 6272. Full resistance to falling 1 kg weight indenter impact from 50 cm height directly to the coating and from the opposite side	ISO 1520. Full resistance of coating to cracking and detachment from a substrate by indentation to 7 mm depth

 Easy-to-apply

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. TUBALL MATRIX can be processed with standard equipment widely used in the coating industry:

Standard single shaft high speed mixer	25 min total dilution time	Quality control to reach particle size ≤ 15 µm

Other benefits provided by TUBALL nanotubes for lining coatings:

• Less influence on rheology compared to other conductive additives

• Low dosage gives greater flexibility in the final formulation and means less need for solvent usage

• Electrical resistivity stable over time and independent of humidity without “hot spots”

• Consistent quality for large industrial batches

• Ease of application and low dosage makes logistics less complex and more efficient
