Various water based and solvent based grades are available. There are Aluminium Silicate based refractory coatings having low reactivity to metal oxide offered in slurry & ready to use form, gas permeable coating having low reactivity to metal oxide offered in slurry form etc. They are recommended for G.I. / S.G. Iron castings. Suitable for Silicate - CO2 systems and other organic binder systems like cold box/hot box/shell/oil sand etc. They can be used by dipping, spraying, brushing or swabbing; also suitable for over pouring method.

Advantages:
• Incorporation of high quality Aluminium Silicate having high thermal resistance & permeability ensure smooth casting finish & free from casting defects
• Excellent suspension properties help to get uniform coverage consistently
• Blend of high quality refractories and good finish ensures good casting peel and saves on fettling costs
