Al2SiO5 Castable Cement

Al2SiO5 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® 740 liquid foam forms lightweight, high strength, machinable, thermally and electrically insulating parts usable to 1260°C. Just mix the ceramic powder with its liquid activator and pour into non- absorbent moulds. Hardens overnight to produce high strength, insulating prototypes and parts.

Can be used up to 1260°C with high temperature structural stability and excellent resistance to oxidizing and reducing atmospheres. Resistant to molten non-ferrous metals, steam most chemicals and solvents.

Suitable for near net shape processing which involves casting a ceramic blank into a shape that requires minimal or no machining to final shapes. Post curing Rescor® 740 improves its machinability.
