TUBALL™ graphene nanotubes, also known as single wall carbon nanotubes, provide permanent electrical conductivity to gelcoats, while preserving light colors and allowing application via spraying.

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

For polyester and vinyl-ester resins, TUBALL™ MATRIX 204 should be used.

Target system	Polyester, vinyl-ester systems
Additive carrier	Plasticizer + stabilizing agent
Additive carrier	Triethylene glycol dimethacrylate + ammonium salt of polyolefin-based derivatives
Product

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.

Full range of electrical resistivity

OCSiAl internal formulation 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 anti-static gelcoats:

Limited impact on viscosity
Low dosage gives greater flexibility in the final formulation
Easy to apply and the low dosage makes the logistics less complex and more efficient
