RTC-70 fine is a pure alumina based powder Al2O3. It can withstand temperatures up to 1790 °C.

It can be mixed with demineralised water. The mixture results in a moulding paste which must be shaped and dried.

This paste can be poured onto all non-absorbent materials. The moulds should have sufficient vents to allow proper casting. 

RTC-70 mouldable ceramic is available in 3.6 kg. 

For larger sizes, please contact us. We offer other moulding ceramics with unlimited applications at high temperatures.
