Characteristic:
This product is non-toxic, odorless, has a small amount of irritation, can dissolve in water, and has excellent dispersing ability, hard water resistance, and bleach resistance.
Features:
1. Each molecule contains two negative charges, has a large dispersing power, has a large solubility in electrolyte solution, and has high stability to strong acids, strong alkalis and salt solutions.
2. Large molecular weight, strong adsorption capacity, high efficiency and low cost when formulating emulsions; latex particle size distribution is narrow and uniform.
3. Strong thermal stability, suitable for emulsification polymerization at 80-120 ℃, without losing surface activity.
Application:
1. Emulsifier in emulsion polymerization, such as vinyl acetate emulsion, polystyrene emulsion, styrene-butadiene emulsion, vinyl chloride / vinylidene chloride emulsion, etc.
2. Used as binder and binding agent in water-soluble phenolic resin.
3. Used as anionic leveling agent in dyes.
4. Used as leveling agent in nylon printing and dyeing.
5. Used as synergist, spreader, wetting agent, penetrant and flow agent in pesticide emulsion.
6. Used as wetting agent, coupling agent and stabilizer in detergent.
7. The construction industry is used as an asphalt stabilizer to improve pavement quality.
8. Used as antistatic agent in polymer film.
9. Additives in the plating solution can control the shape and particle size of the crystal grains.
10. Antistatic agent in rubber industry.
11. The product's high temperature stability and its ability to resist electrolytes make it widely used in geological aspects such as tertiary oil recovery, soil purification, and subsurface repair.
