It is a well know fact that the Foundry Coatings are widely used to improve the surface casting finish and to achieve the best cosmetic look of the castings. But at the same time we all know that the best of the Foundry coating can never achieve this on a bad core or moulds. A conventional foundry using Sodium silicate CO2 gassed binder system uses mostly solvent based refractory coatings. In view of improving productivity, castings quality, to reduce rejection %, to have cleaner environment in the foundry, all modern foundries are shifting to modern resin systems such as phenolic ester cured, cold box resins, shell sand (Hot-Box), Furan Resin, Alpha set etc. Most of these sand resin systems whether for moulds or cores utilizes water based coatings to avoid casting defects such as metal penetration, sand erosion, veining etc.
