Chromogenic Agent ZD-521

1. Brief  introduction

The chromogenic agent ZD-521 is made from special compounds and is mainly used for oxidative coloring in sulfur dyeing. It improves various defects of alum oxidation process in more environmentally friendly approach. It can also be used to reduce the indigo dyeing.

2.Basic traits

Appearance:  colorless transparent liquid

pH value:    8.0-9.0 (1% aqueous solution)

Solubility:   diluted with water at any ratio

3.Characteristics and advantages

☆   It can improve the surface finish, keep good hydrophilicity and handle of the fabric;

☆   The surface of the cloth oxidized with chromium-free oxidizer has no "sour odor".

☆   The oxidation process is easy to control, without causing excessive oxidation.

☆   It can keep the same color fastness as alum oxidation.

4.Application range

Oxidation coloration during vulcanization and vat dyeing

5.Recommended amount

Chromogenic Agent  ZD-521    2-6g/L

Note: Adjust the pH value 3.5-4 with glacial acetic acid when using it.

6. Package and storage 

 Plastic drum/125kg

 Store in a cool and ventilated warehouse with a shelf life of six months.
