SynChem – Resins & Varnishes Voltatex® 4100 1-component-resin
Voltatex® 4100 is a clear, ready-to-use impregnating resin, thermosetting, yellow-brown glazing, styrene-free 1K dip resin based on unsaturated polyesterimide resins.
- single component
- very high capillary activity
- low evaporation losses while processing
- high resin retention in the object
- low draining losses in the oven
- high efficiency due to favourable curing conditionsand
- excellent impregnating results
The cured resin compound is characterized by:
- good resistance against solvent gases and against long term thermal stress
- high bond strength
- low tendency to crack
- tough-elastic compound
Application
- electric motors
- transformers
- suitable for: Insulation systems of thermal class 180 (H)
Standards
Suitable for: Insulating systems up to thermal class H acc. to IEC 60085
- Temperature index according to IEC 60455-3-5: Type 180
- UL file no.: E 101752 (M) Underwriters Laboratories Inc, USA.
- Polybromited Diphenylether 2003/11/EU

Delivery forms
Voltatex® 4100 is supplied in one-way-cans containing 25 kg.
Storage
In closed original cans the resin can be stored for more than 6 months if provided storage temperature does not exceed 25 °C. Opened containers have to be closed imme diately to protect the material from daylight!
Hardening
In order to minimize evaporation of reactive components while curing the impregnated objects should be heated up to the curing temperature in the shortest possible time. The air flow in the curing oven should be kept to the minimum permitted by safety considerations.
Curing time: at 130 °C - 2h
Protection
Cured Voltatex® 4100 is biologically inactive and not dangerous to health. When processing the liquid resin please refer to the Material Safety Data Sheet (MSDS) for Voltatex® 4100.
Cleaning
Once cured Voltatex® 4100 is almost insoluble. Therefore, application equipment should be cleaned regularly with cleaner Voltatex® T050.
All equipment cleaning and maintenance should be carried out in accordance with the equipment manufacturer’s instructions.
Processing
The impregnating resin can be applied by using
- all kind of conventional dip & bake equipment
- continuous and vacuum dip processes
- VPI process
Unlimited tank stability can be achieved as long as Voltatex® 4100 is kept below 25 °C and at least 30 % of the tank content is used and replaced
with fresh resin per month.
