SynChem – Resins & Varnishes Voltatex® 2100 Impregnating varnish
Varnish composed of polyester imide / phenolic resin.
Voltatex® 2100 is a transparent, ready-to-use and heat-curing impregnating varnish composed of polyester imide/ phenolic resin combination.
Particular features:
- fast curing
- hard-eleastic bonding
- compatible with all common magnet wires
The cured varnish is resistant to:
- solvent vapours
- transformer oils
- climate-related stress
- mould infestation
- acids, alkalines and ammonia
Application
Voltatex® 2100 is applicable for:
- insulation systems up to thermal class H, acc. IEC 60085
- in general suitable up to thermal class E-H, depending on curing time and -temperature.
- electric motors
- rotors with thermal and mechanical high stress
Standards
- Thermal class acc. IEC 216: TI 155-165
- Type acc. E DIN IEC 60646-3-2: type 155
- 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.
