Sodium Silicate (Water Glass) is traditional systems that can be easily adapted to any type of foundry sand systems. Mixed sand has very little, if any, odor and the cured sand mass releases easily from pattern or core box. Neither binders nor catalysts are toxic. Sodium Silicate no-bake systems are being used to produce castings in all types of ferrous and non-ferrous foundries using ester catalyst. Sodium Silicate no-bake sands can be used in the foundry to replace normal green sand molding operations and other no-bake binders. They provides improved casting dimensional control and casting finish. Also, casting defects caused by gas as well as expansion defects can be reduced or eliminated. Can be use as binder for furnace top ring and lining furnace.
