IPS PressVEST Premium is an universal, phosphate-bonded investment material for the following Ivoclar Vivadent pressed ceramics: IPS e.max Press, IPS e.max ZirPress, IPS InLine PoM (Press-on-Metal ceramic). IPS PressVest Premium can be used in the popular speed heating procedure as well as with conventional heating methods. The high stability during the preheating phase allows materials with different expansion values to be processed. IPS PressVest Premium is suitable for milled and printed objects made from wax or acrylic. IPS PressVest Premium has only a slight reaction layer, which is very easy to remove, and allows for a silky smooth surface. IPS PressVEST Premium cannot be used for metal casting, due to the high temperatures.
