Other Characteristics

2.6 2.8

A natural fibrous form of talc, gray in color.

Agalite or Talc

Silicate of Magnesia

MgO-32%, SiO2-62%

It gives paper a greasy or soapy feel. and enables it to take a high finish.

Natural Sulfate of Lime

CaSO4.2H2O 100%

A calcium salt that is used for a variety of purposes including:

2.4

building materials. Ammonium Bisulfite

NH 4HSO3

Used in sulfite pulping

Ammonium Zirconium Carbonate (AZC)

CH2O3NH3Zr

Used as insolubilizer, crosslinker & hardener

1.36

AZC is a clear, usually colorless solution, having an odor of ammonia and a pH of approximately 9.5. As a carbonate, it will react with acids, and so should not be used in coating systems below pH 7. In storage, it is stable for up to six months.

Anthraquinone

Anthraquinone

C14H8O2

Added to white liquor (alkaline cooking liquor) to improve pulp yield and to increase the rate of delignification.

1.44

yellow crystalline powder

AntiFoam/Defoamer

To prevent foam (anti-foam) or to destroy it once it has formed (defoamer).

Asbestine

Silicate of Magnesia

MgO-32%, SiO2-62%

It is used as a loading agent in paper manufacture, particularly for blotting papers and board.

APE
