SiO2 castable cement

SiO2 Castable 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.
