Stearylamine Polyoxyethylene Ether AC-1802 is widely used in seven major fields: plastics and chemical fibers, textile printing and dyeing, daily chemicals, industrial auxiliaries, metal processing, mineral flotation, and oil fields. Its core functions cover antistatic, emulsifying, dispersing, conditioning, and corrosion inhibition.

Overview of Industry and Process Applications

Application IndustrySpecific Process/UseCore Function
Plastics and Chemical Fiber IndustryInternal additive antistatic agent, suitable for PE, PP, PS, and synthetic fiber production and processingReduce surface resistance, prevent static accumulation and dust adhesion
Textile Printing and Dyeing IndustryLeveling agent, softener intermediate, suitable for finishing of cotton, wool, synthetic fibers and blended fabricsImprove dye penetration uniformity, impart soft and fluffy hand feel, reduce color spots
Daily Chemical IndustryConditioning agent and cream emulsifier in formulations such as shampoos, conditioners, and body washesImprove wet combing smoothness, provide emulsion stability, adsorb on hair and skin surfaces
Industrial AuxiliariesPesticide emulsifiable concentrates, coatings, inks, industrial cleaning, leather processingEmulsify oil phase components, disperse pigments and solid particles, prevent sedimentation and stratification
Metalworking FluidsEmulsifying and corrosion-inhibiting components in cutting fluids, grinding fluids, and rolling fluidsEmulsify lubrication, assist corrosion inhibition, extend service life of processing fluids
Mineral ProcessingCollector or auxiliary collector for non-metallic minerals such as phosphate rock and potash salt flotationAmine group selectively adsorbs on mineral surfaces, enhance hydrophobicity and bubble attachment
Oil Field AuxiliariesFormulation of demulsifiers, corrosion inhibitors for oil production and pipeline transportationPromote oil-water separation of crude oil emulsions, protect pipeline equipment

Ion Characteristics and Process Compatibility Explanation

AC-1802 is non-ionic in neutral and alkaline environments, with excellent chemical compatibility; under acidic conditions, the amine group protonates to become cationic, which significantly enhances its adsorption capacity on negatively charged substrates (such as fibers, mineral surfaces, and polymers). This convertible characteristic enables it to perform emulsifying, dispersing, antistatic, and conditioning functions under different process conditions.

Key Performance Advantages

  • Forms stable oil-in-water or water-in-oil emulsion systems at low dosages
  • Resistant to acid, alkali, and hard water, adaptable to complex industrial environments
  • Combines durable antistatic properties with dual effects of fiber softening and conditioning
  • Harmful to aquatic organisms; wear protective equipment during operation, and wastewater must be treated to meet discharge standards
