OP-4SA is mainly used in five major fields: emulsion polymerization, textile auxiliaries, leather processing, metalworking fluids, and industrial cleaning.

Core Application Industries and Processes

OP-4SA nonylphenol polyoxyethylene ether ammonium sulfate is a surfactant with both nonionic and anionic characteristics, playing a key role in multiple industrial fields due to its excellent emulsifying, wetting, and dispersing properties.

Detailed Application Distribution

Application Industry Specific Process Functional Role
Emulsion Polymerization Emulsion polymerization of acrylate, styrene-acrylic, pure acrylic, vinyl acetate-acrylic, etc. Highly effective anionic emulsifier, providing mechanical and chemical stability, controlling latex particle size, and improving film formation properties.
Textile Auxiliaries Fiber pretreatment, scouring, level dyeing, finishing Wetting agent, penetrant, leveling agent, improving processing efficiency and dyeing uniformity.
Leather Processing Soaking, degreasing, tanning, fatliquoring Degreasing agent and penetration aid, promoting uniform penetration of chemicals, improving leather softness and fullness.
Metalworking Fluids Cutting fluids, grinding fluids, rust prevention fluids Emulsifier and rust inhibitor, providing emulsion stability, lubricity, and rust protection to the working fluid.
Industrial Cleaning Hard surface cleaning, heavy-duty cleaning Wetting and penetrating component, enhancing detergency.

Application Recommendations

This product is recommended to be used in combination with anionic or nonionic emulsifiers in emulsion polymerization to achieve synergistic effects. The specific dosage should be determined through experiments based on the target system. The product has excellent hard water resistance and can perform stably under weakly acidic to alkaline conditions, making it suitable for high-hardness water environments.
