RTC-60 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-60 is available in different grain sizes and in 2.3 L, 12 L and 23 L.
For larger sizes, please contact us. We offer other moulding ceramics with unlimited applications at high temperatures.
- Resistance to redox

For foundry moulds Final Advanced Materials produces alumina, silicon carbide, silica or zirconia-based cements, which are suited for temperatures between 1,200 and 2,200°C. Zirconia formulations are particularly suitable if a very high resistance to chemicals is required. Alumina cements have better mechanical resistance (>40 MPa in compression). SiC cement is a very good option for molten metal casting, launders, crucibles or nozzles. The choice depends on the cast metal and the temperature (e.g.: aluminium ~700°C, steel >1,500°C) and the thermal shock resistance.
