Aquapour from Advanced Ceramics Manufacturing


AquaPour is a fluid slurry that is castable; hence, it is capable of forming complex shapes. It comes as a dry powder and water is added to activate it. It is most commonly utilized in applications where a mold is filled with the material in the liquid state, and upon setting in the green state (~10-20 min), it can be removed from the tool and placed into an oven to be fully set via thermal dehydration. AquaPour behavior and performance can be adjusted with combinations of water content and ACM’s accelerator and retarder solutions. AquaPour mandrels are porous and need to be sealed before composite processing to prevent resin infiltration.
