The components should be mixed thoroughly to ensure homogeneity. It is important that the side and the bottom of the vessel are incorporated into the mixing process.
- When processing large quantities of mixture the pot life will decrease due to exothermic reaction. It is advisable to divide large mixes into several smaller containers. For industrial parts production we recommend to use a mixing/dosing device

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 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
- Provided that Araldite® LY 3508, Araldite® LY 3585, Araldite® LY 564 or Aradur® 3458 are stored in a dry place in their original, properly closed containers at the storage temperatures mentioned in the MSDS they will have the shelf lives indicated on the labels.
- Partly emptied containers should be closed immediately after use. Araldite® LY 3508 or Araldite® LY 3585 which has crystallized and looks cloudy can be restored to its original state by heating to 60 - 80°C.
