Preserved mechanical properties

TUBALL™ nanotubes, in contrast to traditional conductive agents, maintain the mechanical properties of the original non-conductive powder coating.

Preserved adhesion

ISO 2409. No detachment of coating from a substrate after cross-cut adhesion test. The same 0 class adhesion in epoxy-polyester system after addition of TUBALL™ MATRIX.

Maintained impact resistance

ISO 6272. Hybrid epoxy-polyester system. Full resistance to falling 1 kg weight indenter impact from 50 cm height directly to the coating and from the opposite side.

Retained resistance to cracking

ISO 1520. Hybrid epoxy-polyester system. Full resistance of coating to cracking and detachment from a substrate by indentation to 7 mm depth.

Full range of resistivity

TUBALL™ MATRIX, in contrast to traditional conductive agents, does not increase melt viscosity and provides a full range of resistivity.

    Additional information

    Produce anti-static powder coatings in 2.5 months without changing processing

    The powder coating must be conductive to meet requirements where sensitive electronic equipment needs to be protected from electrostatic discharge due to static build-up. The coating acts as a protective film that will dissipate any static charge accumulating on the surface.

    TUBALL™ graphene nanotubes are an effective alternative to carbon black and conductive mica for conductive powder coatings. Such coatings enhanced with TUBALL™ nanotubes are widely applied on ESD workstation surfaces that must be protected from electrostatic discharge. Widespread applications include:

    • Electronics enclosures
    • Computer workstations
    • Workbenches and work surfaces
    • Shelving
    • Storage organizers

    TUBALL™ graphene nanotubes, also known as single wall carbon nanotubes, can be used in the production of powder coatings in compliance with the IEC 61340-5-1 standard and other ATEX regulations.
