System Preparation

Prefilled components should be stirred and homogenized in the original containers prior to use.

Highly-filled components are heated to 60° to 80C in the original container (e.g. overnight in an oven) to facilitate stirring and removal.

To prepare the casting mix, the resin component should be homogenized in a holding tank at 80° to 90C under a vacuum of 1 to 5 mbar, the hardener component should be stored in a separate holding tank at 30° to 40C under a vacuum of 1 to 5 mbar. A metering system can be used to feed the resin and hardener components to a mixer.
