Components Parts by weight Parts by volume Araldite® LY 3508 100 100 Hardener XB 3403 30 37 - We recommend that the components are weighed with an accurate balance to prevent mixing inaccuracies which can affect the properties of the matrix system.
- 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.

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, Hardener XB 3403 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.
- Epoxy Araldite® LY 3508 which has crystallized and looks cloudy can be restored to its original state by heating to 60 - 80°C.
