SynChem – Resins & Varnishes Voltatex ® 4130 1-component-resin
Voltatex® 4130 is a cloudy, yellow-brown, vinyl toluene based, styrene-free single-component impregnating resin that is ready to use, 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
The cured resin compound is characterized by:
- high thermal endurance
- excellent bond strength
- high thermal and mechanical stability, especially under extreme long term stress
- tough and hard resin compound
Application
- stators
- transformers
- suitable for: Insulation systems of thermal class 180 (H)

Delivery forms
Voltatex® 4130 is supplied in one-way-cans containing 25 kg.
Storage
In closed original cans the resin can be stored for 6 months if provided storage temperature does not exceed 25 °C.
Hardening
In order to minimize evaporation of reactive components while curing the impregnated objects should be heated up to the curing temperaturein 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: 3h
at 150 °C: 1h
Protection
Cured Voltatex® 4130 is biologically inactive and not dangerous to health. When processing the liquid resin please refer to the Material Safety Data Sheet (MSDS) for Voltatex® 4130 and the regulations of your local authority.
Cleaning
Once cured Voltatex®4130 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® 4130 is kept below 25 °C and at least 30 % of the tank content is used and
replaced with fresh resin per month. For optimum process viscosity it is possible to add Voltatex® T032.
