Following are the Main Specifications of Leather Dyes :-
Characteristics: Cationic fixing agent for dyeing
Appearance: Colorless to creamy white liquid
PH value(10% aqua solution): 5.5-6.5
Solid content%: 57.0±3.0
Charge: Cationic
Dilutability: Can be mixed with wather with any proporties
Compatibility: Sedimentation may happen with applied with anionic products. It is well compatible with nonionic and cationic products

Properties and Usage
1. DESOAGEN S: When applied in pretreatment,before dyeing,it can transform the charge to increases the dye ability of anionic dye-stuffs.Thus, it evidently improves the depth of color. In order to avoid sedimentation of dyestuffs, the dyeing operation should be carried out in a fresh bath after pretreatment.
2. When anionic dyestuffs are used to dye the leather with low affinity, an intermediate treatment(sandwich method) should be carried out. There is an evident increase of color depth, brilliance and fullness.
3. When applied after the addition of formic acid and completion of dyeing, the fastness and fullness of color are enhanced.

1.Pretreatment(after neutralization and washing): Float ratio:2.0 55 centi degrees
2.Sandwich dyeing method: After first dyeing and fixation,add 0.3-0.5% DESOAGEN S in the same bath, run 30-40min, then drain, the second dyeing is carried out in a fresh bath.
3.Apply after completion of dyeing, add 0.3-1.0%DESOAGEN S in the same bath, run 40-60min
4.Dilute with hot water before applying.
