NNO-CH of the main component is sodium naphthalene sulphonate formaldehyde as light yellow powder dispersing agent. Its role is to put all kinds of powder reasonably slack in solvent, after a certain amount of charge exclusion principle or polymer resistance effect, make all kinds of solid was suspended in the solvent (or slack liquid)
This product is soluble in water, acid, alkali, salt and hard water, has good diffusion performance. Dispersing agent for use in waterborne coatings is necessary to water soluble, which are selected to be adsorbed on the surface of the powder and water. This product is anion type, which are ionized in water to form anions, has a surface active, adsorbed powder surface. The powder particle in surface adsorpted dispersant is formed double electric layer
Mainly used in disperse dyes, vat dyes, reactive dyes, acid dyes and dyes in the leather as a dispersant. dye of milling efficiency、solubilization、dispersibility are excellent. Can also be used for textile dyeing, wettable pesticide，paper making，electroplating additive，pigment, carbon black, water soluble paint in latex、rubber、building, water treatment agent in oil drilling.
Form Powder Colour Brownish powder Dispersion force ≥100% PH value(1:100) 7-9 Sodium sulphate content ≤5% Water insoluble matter ≤0.1% Calcium and magnesium ions ≤0.15%
1. Disperse dyes or vat dyes of particle fineness processing, the dispersing agent and the dye can be added to the grinding machine and the sand mill together. The dosage of the dispersant is 0.5-3 times of vat dyes or 1.5-2 times of the disperse dyes 2. Pigment pad dyeing：Add dispersant 3-5 g / L in the dyeing bath; add dispersant 15-20 g / L in reducing bath; Leuco acid method: General dispersant dosage is 2-3 g / L. 3. High temperature dyeing of polyester generally can be added to 0.5-1.5 g / L dispersant in the dye bath; 4. Ice dyeing：Add dispersant 2-5 g / L in sodium salt solution bath for base; add dispersant 0.5-2 g / L in the diazonium salt solution bath for color;
1. The product is supplied in 25 kg .Plastic woven bag with lined thick plastic bags is two layer, sturdy and waterproof. Packaging size may vary subject to meet customer requirements，but it need pre-order. 2. The product should be stored in dry warehouse, damp proof. If the powder becomes lumps because of moisture, it still can be used after smashing，the effect is same. The shelf life is 1 years. If the product is overdue, it can be used after testing qualify.
