Foundry Grades

It is specially processed with necessary additives to achieve good thermal conductivity at higher temperature. It is rich sodium montmorillonite clay having good swelling & bonding properties. It is ground to 200 mesh powder having good Green Compression Strength & Dry Compression strength. Primary usage in the production of non-ferrous castings for foundries.

• Generate good green and dry strength and better flow ability with optimum temperature of water.
• High thermal stability.
• Excellent reliability.
• Better mould strength in high pressure moulding.
• Easy to generate sharp add strong mould as edge and corners.
• Generate good strength at lower addition..
• Good control on active clay.

• Mixing ratio depend on sand fineness and its quality,impurities, clay particles and fineness of sand will affect the green strength properties.
