>> Product Introduce
Stearyldimethylhydroxyethylammonium nitrate (SDHAN)
CAS 86443-82-5
Stearyldimethylhydroxyethylammonium nitrate (CAS 86443-82-5) is a cationic quaternary ammonium salt surfactant that appears as a reddish-brown to amber transparent viscous liquid at room temperature, exhibiting excellent solubility in water and a wide range of polar organic solvents such as acetone, ethanol, butanol, benzene, and chloroform. This versatile antistatic agent is primarily employed in the textile industry for synthetic fibers including polyester, nylon, and polyvinyl chloride, where it effectively eliminates static electricity during spinning, weaving, and finishing processes to prevent fiber entanglement, thread breakage, and dust adhesion. Beyond textile applications, it serves as an effective antistatic additive for plastics and rubber products such as PVC, polyethylene, and nitrile rubber, reducing surface resistance to prevent electrostatic hazards, while also functioning as a leveling agent for acrylic fiber dyeing and as an asphalt emulsifier in emulsion formulations. The product remains stable in dilute acid and alkali solutions, withstands processing temperatures up to 180°C, and is compatible with cationic and nonionic surfactants but incompatible with anionic counterparts.
>> Main Uses
Stearyldimethylhydroxyethylammonium nitrate (SDHAN, CAS 86443-82-5) is primarily utilized as a cationic antistatic agent in the textile industry for synthetic fibers such as polyester, polyamide (nylon), and polyvinyl chloride, where it is applied during spinning, weaving, and finishing processes to effectively eliminate static electricity, prevent fiber entanglement and thread breakage, and reduce dust adhesion at typical dosages of 0.2% to 0.5% by weight of the fiber. In the plastics and rubber industry, it serves as an antistatic additive for materials including PVC, polyethylene, polyester, and nitrile rubber, migrating to the surface to form a conductive layer that reduces surface resistance and prevents electrostatic accumulation, with typical addition levels ranging from 0.5% to 2% in plastic formulations. Additionally, this versatile surfactant functions as a leveling agent for polyacrylonitrile (acrylic) fibers to promote uniform dye uptake, as an asphalt emulsifier in emulsion formulations to improve stability and workability, and as a static eliminator for nitrile rubber spinning cots and silk processing, making it a valuable additive across multiple industrial applications where electrostatic control is essential.
