  • UL-temperature class: 200

Delivery forms

Voltatex® 2100 is delivered in 25 kg one-way compounds.

Base

Polyester imide / phenolic resin

Color

Transparent

Storage

The resin can be stored for up to 12 months at max. 25 °C if sealed correctly in original containers.

Hardening

  • Thermal class E: 4-6 h at 120 °C
  • Thermal class B: 4-6 h at 130 °C
  • Thermal class F-H: 6 h at 150 °C

Protection

Cured Voltatex® 2100 is biologically inactive and not dangerous to health. When processing the liquid resin, please refer to the Material Safety Data Sheet (MSDS) for Voltatex® 2100.

Cleaning

Cured Voltatex® 2100 is almost insoluble. Therefore, application equipment should be regularly cleaned with cleaner Voltatex® T050 or T060. All equipment cleaning and maintenance should be carried out in accordance with the equipment manufacturer’s instructions.

Processing

Voltatex® 2100 is delivered ready-to-use. The consistency can be lowered if necessary with Voltatex® T022.
