TUBALL™ graphene nanotubes enhance tank coatings by providing stable, uniform electrical conductivity while preserving the original mechanical properties of the material. Nanotubes enable the creation of light-colored, durable coatings with ESD protection using standard production technology and equipment.
Graphene nanotube-enhanced anti-static lining coatings comply with international standards and recommendations, including EN 14015, TRbF 401, NFPA 77, and other regional versions. By installing these coatings, manufacturers can overcome the limitations of conventional conductive agents, while end-users can simplify tank visual inspections and regular maintenance.
Conductive lining coatings are specialized protective layers designed to prevent static charge buildup inside storage tanks and containers. By incorporating conductive materials, these coatings ensure safe electrostatic dissipation (ESD), reducing the risk of sparks and explosions when handling flammable liquids or powders.
They are widely used in industries such as chemicals, oil and gas, and pharmaceuticals where safe storage and transportation of hazardous materials are critical. These coatings help comply with safety standards and improve maintenance efficiency while preserving the integrity of the stored materials.
TUBALL™ graphene nanotubes provide stable electrical conductivity in tank lining coatings, offering a superior alternative to graphite powder and conductive mica. These ultra-strong, electrically conductive, flexible nanotubes are effective at ultralow dosages—dozens of times lower than conventional additives—delivering unmatched performance. The result is electrostatic dissipative, durable, high-performance coatings with maintained mechanical properties and required lighter colors.
TUBALL™ graphene nanotubes in epoxy coatings provide stable, permanent surface resistivity of 10⁴–10⁹ ohm/sq that remains consistent over time and is independent of humidity, with no insulating spots.
In contrast to conventional conductive additives, TUBALL™ nanotubes unique morphology and the ultralow dosage required help preserve high bond strength and adhesion, as well as resistance to wear, abrasion, and impact. This makes it possible to avoid time-consuming and costly remedial maintenance.
The tiny amount—just 0.1 wt.%—of 10% TUBALL™ nanotube concentrate required to achieve permanent electrical conductivity in lining coatings allows light colors to be preserved. A wide range of available colors accelerates visual inspections and improves servicing efficiency. This also enables a servicing company to apply a light-colored top layer. Any contrast between top and base layers indicates insufficient coating thickness, making it easy to identify areas that need maintenance. Additionally, during operation, a light-colored lining makes it much easier to inspect for defects on the internal surface.
