Prefere 4050 adhesives are simple to prepare. Both resin and hardener are liquids, and are mixed in a 1:1 ratio. It is essential that hardener Prefere 5750 is well stirred pouring from the container, as the filler can occasionally separate. Add the required amount of the hardener Prefere 5750 to the Prefere 4050 and mix thoroughly. The proportions may be measured by weight or volume.

Handling and Storage

Consult Safety Data Sheet prior to use.

Prefere 5750 should be stored firmly sealed in the original container in a cool (ideally 5 – 20°C) dry place. Shelf life under these conditions is at least 18 months.
