Castable cement SiO2

Application of silica SiO2 castable ceramic cement.

Rescor® Castable Ceramics are available in 6 refractory compositions offering the ultimate selection of ceramics to the materials engineer. Now, an unlimited number of high-temperature applications, requiring custom ceramic shapes, can be easily solved. Just mix the ceramic powders with their liquid activators and pour into any non-absorbent moulds.

Rescor® Castable Ceramics harden overnight to produce highly detailed ceramics, usable to 4000 °C. They offer excellent resistance to high temperature, thermal shock, molten metals, oxidizing and reducing atmospheres, erosion, most acids and alkalise.

Rescor® 750 easily cast 2000-pound moulds measuring 6 feet in length to be used for forming and curing composite materials.
