Aluminium powder is used as a filler in the making of moulding material which is capable of conducting heat and being machined. In addition, it can be used to lend a metallic silver gloss to casting resins. The mixing ratio is 1 to 1.5 times parts per weight in relation to the total mixture and it is added to the individual components before mixing them together. Aluminium powder can be used for other purposes than just as a filler: when sprinkled on paste or spray adhesive it can create decorative surfaces in architectural models; when stirred into acrylic binders (CAPAROL) a very interesting coating material is produced.
