Sodium Silicate for Making Foundry , sodium silicate investment casting - Budget Casting Supply

Sand is mixed with a binder to form a solid "sand core". A core must porous enough to allow gas to escape from the casting, while still blocking the molten metal. It should also be easily removed from the finished casting. Sodium Silicate is used as the binder that "glues" the sand together in cores. For example, imagine making a cannon.investment castingsSodium silicate process : In China, sodium silicate process is also called water glass process.
