Graphene nanotubes for anti-static silicone PSA: transparency and stable electrical conductivity

TUBALL™ nanotubes improve the electrical conductivity of silicone PSA without drawbacks in other important properties such as transparency and wet-out performance, and without affecting the coating process.

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

Key benefit 2: Maintained other key properties

Using TUBALL™ MATRIX in combination with PEDOT primer allows the technological performance to be maintained:

  • No impact on Pt curing system
  • Peel-off strength
  • Transparency
  • Wet-out performance

Peel-off strength

Key benefit 3: Standard processing and mixing equipment

TUBALL™ MATRIX can be processed with standard equipment widely used by PSA resin and additive manufacturers.

Other benefits

  • Extremely low loadings of TUBALL™ that preserve properties
  • Colors and transparency are retained
  • Carrier compatible with silicone PSA resin
  • No oil migration on surface
