Ecolink Hongkong Limited

Today there is increasing demand for granular fertilizers from the crop nutrition industry which have a favorable appearance. Ecolink has developed a broad range of coloring agents based on dyes and/or pigments to treat the entire fertilizer granule from the inside out, including colorants that can modify the color, sheen, and translucency of the fertilizer granule surface as desired. Our line of coloring agents includes oil-soluble colorants, aqueous colorants, and colored coating agents.

Ecolink also designs and installs optimal application systems for our coloring agents. These application systems can be designed to include colorimeters to detect subtle changes in fertilizer color, shade, and intensity and to synchronize these detection devices to dosing controls to maintain consistent colorant adherence to fertilizer color specifications.
