Components Parts by weight Araldite® LY 3508 100 Aradur® 1571 28 Accelerator 1573 3 - Mix Aradur® 1571 with Accelerator 1573 to get homogeneous paste, this pre-mix has a long shelf life at RT (min. 2 weeks) The pre-mix Aradur® 1571 / Accelerator 1573 is blended into the Araldite® LY 3508 and mixed homogeneously just before the towpregging process.
- 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.

Safety & Health
- 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 and Aradur® 1571, Aradur® 1573 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.
