Carbon Additive

Sandaid-50 – is a lustrous carbon additive specially designed with selected volatile content for iron foundry green sand.
Exoaid–61 - is a sand additive to eliminate sand expansion defects such as scabs, buckles.
Exoaid-61 high burn-out temperature contents and results in lower concentration of dead clay. This improves permeability, reduces moisture requirements and gives better all-round sand properties over a longer life-cycle.
Addition % of Exoaid – 61 is 0.5 - 1.0 % in the facing sand.
If it is added in total sand system than 0.05 – 0.1% is sufficient.
Exoaid–81 – is an anti veining sand additive. It is free from contaminants such as oil, moisture, acid salts, slag and gangue minerals.
