Uses:

 Dispersant NNO is mainly used as a dispersant in disperse dyes, reduced fuels, reactive dyes, acid dyes and leather dyes, with excellent grinding efficiency, solubilization and dispersibility; it can also be used as a dispersant in textile printing and dyeing, and wettable pesticides. Dispersants for papermaking, electroplating additives, water-soluble paints, pigment dispersants, water treatment agents, carbon black dispersants, etc. Dispersant NNO is mainly used in industry for pad dyeing of vat dye suspension, leuco acid dyeing, and dyeing of dispersive and soluble vat dyes. It can also be used for dyeing silk/wool interwoven fabrics, so that there is no color on the silk. The dispersant NNO is mainly used in the dye industry as a dispersion aid in dispersion and lake manufacturing, rubber emulsion stability, and leather tanning aid.

Using conditions:

(1) Diffusing agent NNO is used as a dispersant, dispersant and filler for vat dyes, disperse dyes or vat dye particles can be processed with dispersant N and dyes together with the grinder and sand mill. The amount of dispersant N is 05-3 times that of vat dyes or 1.5-2 times that of disperse dyes, and some can be left as a filler when the dye is commercialized;

(2) Dispersant NNO is used for dyeing with vat dyes: County floating body pad dyeing method: In the pad dyeing bath, generally add diffusing agent N3-5 g/L, in the reducing bath generally add diffusing agent N15-20 g/L; leuco acid method: Yixiu diffusing agent N dosage is 2-3 g/L

 (3)  Diffusing agent NNO is used as disperse dye dyeing: Generally, 0.5-1.5 g/L, dispersing agent N can be added to the dyeing bath during high temperature and high pressure dyeing of polyester;

(4) Dispersant NNO is used as ice Dyeing dyeing: to improve leveling and friction fastness, the amount of diffusing agent in naphthol base bath is generally 2-5 g/l, and the amount of diffusing agent N in color developing bath is generally 0.5-2 g/l.

Packaging:

25kg woven bag lined with plastic bag for storage and transportation; the  Diffusing agent NNO  packaged in the finished product must be handled and unloaded lightly. It should be stored in a cool, dry and ventilated warehouse. The shelf life is two years.
