Octadecyl polyoxyethylene ether AC-1812 is mainly used in seven major industries: textile printing and dyeing, synthetic fibers, plastics, metal processing, pesticides, leather, and papermaking. The core processes include high-temperature and high-pressure leveling, spinning oil agents, antistatic treatment, emulsification and dispersion, and surface protection.

Detailed Application Industries and Processes

IndustryProcess/ApplicationFunction Description
Textile Printing and DyeingHigh-temperature and high-pressure dyeing of polyester and its blendsEfficient leveling agent, improves dye dispersion, ensures uniform color consistency
Synthetic Fiber ProcessingSpinning oil agent componentProvides antistatic and smoothness properties, reduces fiber friction, improves spinnability
Plastics IndustryInternal additive antistatic treatmentLong-term reduction of surface resistance, suitable for packaging films, electronic devices, etc.
Metal Processing and Rust PreventionSurface cleaning, pickling corrosion inhibition, rust preventionForms a protective film to slow down corrosion, improves subsequent processing quality
Pesticide FormulationsEmulsification and dispersion of emulsifiable concentrates, microemulsions, and water suspensionsEnhances stability and application effectiveness of the liquid formulation
Leather ProcessingFatliquoring and dye levelingImproves leather softness and color absorption uniformity, reduces the risk of uneven color
Papermaking IndustryDeinking of waste paper and fiber dispersionPromotes ink removal, improves pulp cleanliness and paper uniformity

Core Function Summary

AC-1812 is a nonionic surfactant (exhibiting cationic properties under acidic conditions), integrating multiple functions such as emulsification, dispersion, antistatic, smoothing, and corrosion inhibition. It is resistant to acids, alkalis, and hard water, has good thermal stability, and can reduce the variety of auxiliaries in the formulation.
