  • 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.
