ApplicationofPotassium Aluminium Fluoride (PAF)

• PAF is used as Magnesium removal flux in the smelting of secondary aluminium to reduce or remove the Mg from the Aluminium melts.
• It is used in the manufacture of grinding wheels (filler/binder) and other abrasive products.
• Other common applications of PAF: as the additive to roofing shingles, where it acts as an alkaline Ph adjuster and flame retardant. It can also be used as color additive in the coatings for roofing granules.
• Glass producers use the PAF for pacification or to cloud the glass giving it a milky white color.
