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.
- 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.
