<span style="font-family: arial, helvetica, sans-serif;"><strong>Foundry bentonite</strong> is in-organic treated bentonite clay which is utilized in foundry to bind the sand grains into desired shapes. <strong>Foundry bentonite</strong> helps in retaining the mechanical shape of the mould by making the particles of sands adhere to it and also making the surface impermeable. </span>

<span style="font-family: arial, helvetica, sans-serif;">Strength and fusion point are the two important properties desired for selecting bentonite. Primary use is in the production of non-ferrous castings. </span>

<span style="font-family: arial, helvetica, sans-serif;">Mixing ratio depends on the sand fineness and its quality, impurities, clay particles and fineness of sand </span>
