System 1 System 2 System 3 Araldite® LY 3514
100 100 100 Aradur® 1571 20 20 20 Accelerator 1573 1 2 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 3514 and mixed homogeneously just before the prepegging 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 the products described above are stored in a dry place in their original, properly closed containers at the above mentioned storage temperatures they will have the shelf lives indicated on the labels.
- Partly emptied containers should be closed immediately after use.
