Outdoor electrical insulation material for medium and high voltage application, such as current and potential transformers
- System Preparation
The following is the suggested preheat temperature of ARALDITE® Resin and ARADUR® Hardener:
ARALDITE resin: 50°C for 6 to 12 hrs
ARADUR hardener: room temperature
Filler: 80°C - 110°C for 6 to 12 hrs depends on process condition.Mix all of the components together very thoroughly (the mixture temperature will be reached at or about 60°C. If lower mix viscosity is expected, preheat resin at higher temperature but not exceed 80°C) under vacuum. Proper mixing will result in:
- Better flow properties and reduced tendency to shrinkage.
- Lower internal stresses and therefore improved mechanical properties on object.
- Improved partial discharge behaviour in high voltage applications.
For the mixing of medium to high viscous ARALDITE casting resin systems and for mixing at lower temperatures, it is recommended special thin film degassing mixers that may produce additional self-heating of 10 - 15°C as a result of friction. For low viscous ARALDITE casting resin systems, conventional anchor mixers are usually sufficient.
In larger plants, two pre-mixers are used to mix the individual components (resin, hardener) under vacuum. Metering pumps then feed these premixes to the final mixer or a continuous mixer. The individual premix can be stored at elevated temperature (about 60°C) for up to about 1 week, depending on formulation. Intermittent agitation during storage is advisable to prevent filler sedimentation. Mixing time can vary from 0.5 to 3 hours, depending on mixing temperature, quantity, mixing equipment and the particular application. The required vacuum is 0.5 to 8 mbar. The vapour pressure of the individual components should be taken into account.

Safety & Health
- Handling Precautions
Protective clothing
Yes Gloves Essential Arm protector Recommended when skin contact likely
Goggestery diasses
Yes Respirator/dust mask
Recommended Skin protection before starting work
Apply barrier cream to exposed skin
Skin protection after washing
Apply barrier or nourishing cream
Skin protection cleansing of contaminated skin
Dab off with absorbent paper, wash with warm water and alkali-free soap, then dry with disposable towels. Do not use solvents
Clean shop requirements
Cover workbenches, etc. with light coloured paper. Use disposable breakers, etc.
Disposal of spillage
Soak up with sawdust or cotton waste and deposit in plastic-lined bin
Ventilation: of workshop
Renew air 3 to 5 times an hour
Ventilation: of workplace
Exhaust fans. Operatives should avoid inhaling vapours.
- First Aid Information
- Contamination of the eyes by resin, hardener or casting mix should be treated immediately by flushing with clean, running water for 10 to 15 minutes. A doctor should then be consulted.
- Material smeared or splashed on the skin should be dabbed off, and the contaminated area then washed and treated with a cleansing cream (see above). A doctor should be consulted in the event of severe irritation or burns. Contaminated clothing should be changed immediately.
- Anyone taken ill after inhaling vapours should be moved out of doors immediately.
Storage & Handling
- Storage Conditions
Store the components dry at 2 - 40°C, in tightly sealed original containers. Under these conditions, the shelf life will correspond to the expiry date stated on the label. After this date, the product may be processed only following reanalyzes. Partly emptied containers should be tightly closed immediately after use.
