Application Details

The material fits very well all requirements for manufacturing of large articles with special dosing and metering equipment because of it`s low viscosity.

  • Insulators and cable accessories
  • Manufacturing of large articles
  • Injection molding or special dosing equipment

Processing

The A and B components are delivered ready to use in 20 kg pail and 200 kg drum kits. With adequate metering equipment, they can be pumped directly from the original containers into the injection molding machine and mixed by a static mixer. The mixing ratio is 1 : 1.
