APC                                                   Natural Bone Ash

Aluminium Protective Coating

Fine grained homogeneous powder , obtained by careful calcination of animal bones, which is  used in aluminum industry as a protective coating.
Very appropriate for use in direct chill casting of ingots and billets.
Could be applied on ladles, launders, troughs, tundishes , filter boxes and vessels, inhibiting sticking of metal to them.
Another common use is to protect all metal equipment and tools exposed to molten metal and in floor areas around mold stations, furnaces and ladles.
