Pue to its unique physical and chemical properties,the sand has the following charateristics and advantages:
- Prevention of sand expansion defects,especially finning/veining
- Elimination of gas-forming additives
- Prevention of reactions between metal and moulding sand
- Prevention of metal penetration
- Reduction of core weight
- Improved flowability of moulding sand
- Influence on the formation of microstructure
- Pouring of thin-walled castings
