CarboCond

CarboCond are electrically conductive epoxy resins filled with carbon nanoparticles. They exhibit very much improved mechanical properties compared to conventional systems. 

Products of the CarboCond series are electrically conductive, solvent-free and stable crystalizing epoxy resins. They consist of low-molecular bisphenol A and bisphenol F components, and contain carbon nanoparticles. The electrical conductivity of CarboCond can be optimized for a very wide selection of applications by simply varying the carbon concentration.

CarboCond exhibits numerous advantages compared to conventional systems filled with carbon black or graphite:

  • unequaled electrical conductivity (specific resistance in the region of 10² Ω ∙cm)
  • substantially improved mechanical properties compared to commercial, electrically conductive epoxy resin systems
  • adjustable electrical conductivity through matched carbon content
  • obtainable in different versions, e.g. for mold making or coatings

CarboCond products have dynamic viscosity of 3 to 13Pa·s. They consist of low-molecular epoxy resins based on bisphenol A and F, and contain carbon nanoparticles plus graphite.

Aimed at as wide a range of applications as possible, CarboCond is obtainable in two basic types for different viscosity and hardening parameters:

  • CarboCond 171, with dynamic viscosity of approx. 13 Pa∙s, is suitable for cold, warm or hot hardening
  • CarboCond 471 is reactively diluted, its dynamic viscosity is approx. 3 Pa∙s, and it is suitable for cold or warm hardening.

The two systems come in three different ranges of conductivity:

  • 0.1 weight % carbon nanoparticles, specific resistance 105 to 107 Ω ∙cm
  • 0.4 weight % carbon nanoparticles, specific resistance 103 to 105 Ω ∙cm
  • 0.6 weight % carbon nanoparticles, specific resistance 102 to 103 Ω ∙cm

CarboCond can be used wherever very high electrical conductivity is needed, e.g.

  • Floors
  • Coatings
  • cast parts
  • ESD protective components

CarboCond products are compatible with very different epoxy resin systems, and can also serve as a master batch in various concentrations. The resulting specific resistance will implement diverse standards in the area of ESD/explosion protection.

A number of aminic and anhydrous hardeners are obtainable for CarboCond.
