Evacuation

From Latin vacuus - free, empty

Ideally, the vacuum refers to a completely empty space, free of material. Such a vacuum is created by pumping out (evacuating) a space or closed container. In other words, by removing from the container the gases contained therein.

In the case of cast resins, evacuation is used in order to remove the air that has adhered to the cast resin after being introduced by the mixing and stirring process, thereby allowing bubble-free curing.
