4. Main Application Fields
Based on its HLB value and performance characteristics, Teric N5 is widely used in multiple industrial fields:
- Chemical Synthesis Field: Used as an organic synthesis intermediate and reaction medium, and as a surfactant in microemulsion systems for the preparation of nanomaterials (e.g., the NP-5/cyclohexane system can be used to prepare 8YSZ nanopowders below 30 nm and Rh/SiO₂ catalysts, etc.).
- Industrial Additive Field:
- Emulsifier: Used in the preparation of water-in-oil (W/O) or oil-in-water (O/W) emulsions, suitable for systems such as coatings, inks, and lubricating cutting oils.
- Dispersant: Improves the dispersion uniformity of pigments and fillers in the system, enhancing product stability.
- Coupling Agent: Promotes the interface bonding between inorganic and organic materials, optimizing the performance of composite materials.
- Rust Inhibitor and Antifreeze: Plays dual roles of rust prevention and antifreeze in metalworking fluids and industrial coolants.
- Other Applications: Used as a leveling agent and detergent in the textile industry; as a degreaser and cleaning agent in the metal processing field; and as an emulsifying aid in the pesticide field to improve the stability of pesticide efficacy.
