  • 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 material on the sides and bottom of the vessel are incorporated during 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.

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 1564 and Aradur® 3475 are stored in a dry place in their original, closed containers at the recommended storage temperatures, shelf life will be as indicated on the product labels.
  • Partly emptied containers should be closed immediately after use.
