Rapid-fire, carbon-free, phosphate-bonded investment that produces ultrasmooth, precise castings quickly and easily. It is easy to divest and resistant to fracture, making it suitable for all crown-and-bridge dental alloys. Once it has set (20 minutes after investing), it can be placed directly into a preheated furnace at final temperature. There is no need for progressive heat-up: the investment can be fired immediately after bench setup time.
