SPECIALTY CHEMICALS

Produced by treating ilmenite with sulfuric acid. The most widely used white pigment because of its brightness, high opacity and refractive index. Used in paints, plastics, paper, ink and other applications.

Produced by treating rutile with chlorine, carbon and oxygen. The most widely used white pigment because of its brightness, high opacity and refractive index. Used in paints, plastics, paper, ink and other applications.

Titanium dioxide with small, isolated and sharply developed tetragonal crystals produced by sulfate process. Used in ceramics, textile, rubber and other applications.

Carbon black is produced by the incomplete combustion of coal or petroleum products in a limited supply of air. It is used as a colorant and reinforcing filler rubber products; pigment in plastics, paints, and ink.

Iron oxides are inexpensive, strongly colored pigments, available in a variety of colors (black, red, yellow).

Stearates are metal salts of stearic acid. Zinc stearate is used in plastics and rubber as a release agent. Calcium stearate improves pigment wetting in color concentrates, it accelerates fusion and improves flow in rigid PVC.
