DOWFAX 2A1 is a high performance anionic surfactant produced by DOW. This product has the characteristics of strong adsorption capacity, large dispersion force, strong relay and so on. It shows excellent stability not only in strong acid, strong base and salt solution, but also in high shear and other conditions. As a result, DOWFAX 2A1 is widely used in emulsion polymerization, textile industry, detergent, pulp and paper, oil extraction and many other industries.

DOWFAX 2A1 Main features:
1. DOWFAX 2A1 each molecule contains two negative charges, large dispersion force, large solubility in electrolyte solution, high stability to strong acid, strong base and salt solution.
2. DOWFAX 2A1 has high molecular weight, strong adsorption capacity, high efficiency and low cost when preparing emulsion; The distribution of latex particle size is narrow and uniform.
3. DOWFAX 2A1 has strong thermal stability and is still suitable for emulsification polymerization at 80-120℃ without loss of surface activity.
4. DOWFAX 2A1 has good mechanical stability. The experimental results show that DOWFAX 2A1 emulsion shows remarkable stability even under higher conditions.
5. DOWFAX 2A1 has high oxidation stability. At room temperature, changes occur only under the action of very strong oxidants: at 50 ℃, the strongest oxidants take several hours to act.
6. DOWFAX 2A1 has low toxicity. At 1% concentration, contact with skin or eyes will only produce temporary pain and irritation; But at higher concentrations (>10%), try to avoid contact with eyes or skin.
1. Emulsion polymerization: styrene butadiene latex emulsion, polystyrene emulsion, polyvinyl acetate emulsion
2. Textile dyeing liquid: dyeing liquid
3. Metal cleaning: soaking tank cleaning liquid, steam cleaning, electrolyte cleaning liquid
4. Petroleum industry: petroleum mining in the third stage. In the emulsification of natural oleic acid, it is used as an emulsifier to isolate acid silt.
5. Phenolic resin
