Industrial Pigmentation

Pigments are used for colouring of products such as paint, plastic, glass, tiles and bricks. Most pigments used in manufacturing  are dry colourants represented as a fine powder. This powder is added to a relatively neutral or colourless material that acts as a binder.

African Pegmatite is the producer of such pigments for mainly the glass, brick, cement, rubber and tile industries. Below is a showcase of the pigments we offer at African Pegmatite
