- Processing Information
- Because of the tendency to sedimentation of the filler, pre-filled components in principle require stirring before removal from the original containers. To avoid errors in dosage, this step is especially important when removing only part of the contents. Prefilled ARALDITE® component is heated to 40°C - 60°C in the original container to facilitate stirring and removal.
- In preparing the casting mixture, the ARADUR® hardener component is thoroughly stirred into the pre-mixed resin component. Brief degassing of the ARALDITE® casting mix under a vacuum of 5 – 10 mbar improves homogeneity as well as the dielectric properties of the casting.

Safety & Health
- Disposal
Regular procedures approved by national and/or local authorities
- Handling Precautions
protective clothing yes gloves essential arm protectors recommended when skin contact likely
goggles/safety glasses yes respirator/dust mask recommended Skin protection Apply barrier cream to exposed skin.
before starting work Apply barrier or nourishing cream.
after washing Dab off with absorbent paper, wash with
Cleansing of contaminated skin 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.
of workplace Exhaust fans. Operatives should avoid inhaling vapours.
- First Aid
- 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. In all cases of doubt call for medical assistance.
Storage & Handling
- Storage Conditions
- Prefilled, liquid products always show small filler sedimentation.
- Before partial use we recommend to stir up carefully the components or to use each container as complete unity.
- Store the components in a dry place at 18-25°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 after reanalysis.
- Partly emptied containers should be tightly closed immediately after use.
