Octadecylamine polyoxyethylene ether AC-1812 (CAS No.: 26635-75-6) is a nonionic surfactant with excellent performance. Its molecular structure combines a long-chain alkyl group (octadecyl chain) with 12 polyoxyethylene chain segments, exhibiting cationic characteristics under acidic conditions. This unique molecular design endows the product with multiple functions such as excellent emulsification, dispersion, antistatic, smoothing, and corrosion inhibition, making it widely used in many industrial fields.
The core advantage of this product lies in its wide pH adaptability and hard water resistance, unaffected by calcium and magnesium ions, maintaining stable surface activity even under harsh conditions such as high temperature and high pressure. In the textile printing and dyeing industry, it plays an irreplaceable role as a core component of high-temperature and high-pressure leveling agents for polyester fibers. In the plastics industry, it provides long-lasting antistatic effects through internal addition. In the metal processing field, it combines cleaning, corrosion inhibition, and rust prevention functions, achieving multiple uses in one agent.
In terms of product form, AC-1812 appears as a light yellow to yellow paste or viscous liquid, with good water dispersibility and excellent thermal stability, suitable for high-temperature processing processes. These characteristics make it an ideal choice for reducing the types of auxiliaries and optimizing costs in industrial formulations.
| Industry Field | Application Process/Scenario | Function |
|---|---|---|
| Textile Printing and Dyeing | High-temperature and high-pressure dyeing of polyester and its blended fabrics | As an efficient leveling agent, improves dye dispersion, ensures uniform color consistency, and guarantees dyeing reproducibility |
| Synthetic Fiber Processing | Component of spinning oil agent | Provides antistatic properties and fiber smoothness, reduces fiber friction, and improves spinnability |
| Plastics Industry | Internal addition type antistatic treatment | Long-term reduction of surface resistance of plastics, preventing static electricity accumulation, suitable for packaging films, electronic devices, etc. |
| Metal Processing and Rust Prevention | Surface cleaning, acid pickling corrosion inhibition, rust prevention treatment | Forms a protective film to slow down corrosion, protect metal substrates, and improve subsequent processing quality |
| Pesticide Formulations | Preparation of emulsifiable concentrates, microemulsions, and aqueous suspensions | Efficient emulsification and dispersion, enhancing drug liquid stability and application effects |
| Leather Processing | Fatliquoring and dyeing processes | Improves leather softness and dye uptake uniformity, reducing the risk of uneven color |
| Papermaking Industry | Deinking of waste paper and fiber dispersion | Promotes ink detachment, assists fiber dispersion, improves pulp cleanliness and paper uniformity |
When using AC-1812 in different industries, the following points should be noted: In high-temperature and high-pressure leveling for textiles, it can be compounded with other dyeing auxiliaries, utilizing its cationic characteristics under acidic conditions to enhance affinity for polyester fibers. In plastic antistatic applications, it is mixed into the base material via internal addition, and the dosage should be adjusted based on the resin type and target resistance value. In metal processing cleaning formulations, it can be compounded with nonionic or anionic surfactants to achieve synergistic effects.
In the field of pesticide formulations, AC-1812 is particularly suitable for use in emulsifiable concentrate and microemulsion systems. Its excellent emulsification and dispersion capabilities effectively improve the dispersion uniformity and emulsion stability of active pesticide ingredients. In papermaking deinking processes, it is recommended for use under neutral or weakly alkaline conditions to fully exert its dual effects of ink detachment and fiber dispersion.
