Mix Ratio

  • 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).
