Liquid colorants are concentrates of various pigments/ dyes dispersed in a liquid system. Excellent affinity of the dispersions on the plastic granules affords ease of working and requires lower loading levels. The coloring of plastics for large scale production by injection moulding, blow moulding or extrusion requires considerable quantities of color.

These colorants enable lower coloring costs while increasing color uniformity and minimizing adverse effects on physical properties. Cost savings also result from lower inventories, shorter production cycles, increased yield, lower housekeeping costs, energy savings, color change etc.

Liquid colorants and additives, alone or in combination, are normally dosed on-line directly into the natural plastic granulate. The dosing pump is easy to operate and maintain and does not demand very high skills.

The vehicle is compatible with almost all polymers and acts as a dispersant for the colorant internally as well as into the polymer matrix. It is non-extractible, inert, thermally stable upto 320�C and moisture-free.
