and furan. A highly alkaline phenolic resin generally containing up to 25% potassium hydroxide is used as binder in ester no bake process [4]. No bake process is another name for resin bonded sand casting in which resin is self-setting at room temperature. In phenolic-ester no bake mould, 1.5 – 2% of the phenolic resin (based on the weight of sand) is first blended into the sand,
