Zirconia embedding cement

These high temperature potting compounds offer temperature stability plus excellent chemical, solvent and electrical resistance. Durapot 800 series is available packaged in either Quart (US), or Gallon (US) packs. Cure times can be accelerated by mild heat 65ºC to 95ºC, whilst post cures @ 120ºC will improve moisture resistance.

Durapot® 814 was formulated for use where a fast cure is required. Just mix and apply. Will cure in 5 minutes at 80°C - 108°C or overnight at room temperature. It is an excellent choice for production applications.

FAQs that can help you in this category

Which high-temperature ceramic cement should I choose to manufacture foundry moulds?

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.
