Basic Information
- Chemical Formula: C3n+3?H6n+10?On?N2?, usually expressed as CH3?CH(NH2?)CH2?(OCH2?CH(CH3?))n?NH2?.
- CAS Number: 9046 - 10 - 0.
- Appearance: Usually colorless to light yellow liquid.
- Odor: Slight special odor.
- Solubility: Soluble in organic solvents such as ethanol, ethylene glycol ethers, ketones, aliphatic hydrocarbons, and aromatic hydrocarbons. Some products like D - 230 are soluble in water, D - 400 is partially soluble in water, and D - 2000 is insoluble in water.
Product Types
Commercial polyetheramines include monofunctional, difunctional, and trifunctional types, with a molecular weight range from 230 to 5000. Specific products are divided into the trifunctional T series and the difunctional D series and E series, such as D230, D400, D2000, T403, T5000, etc1.
Main Properties
- Good Adhesiveness: It can form a firm bond between various substrates such as metals, plastics, and rubbers, and is widely used in adhesives, coatings, and other fields.
- Strong Chemical Stability: It has good stability in common acids, alkalis, and solvents, and can be used to prepare corrosion - resistant materials.
- High Thermal Stability: It can maintain physical and chemical properties in high - temperature environments, and is suitable for high - temperature adhesives and other products.
- Excellent Mechanical Properties: It has high strength, high toughness, and high tensile elastic modulus, and can be used to prepare high - performance elastomers.
- Good Weather Resistance: It can resist the erosion of ultraviolet rays, oxygen, and moisture, and is widely used in outdoor buildings, waterproof coatings, and other fields.
- Adjustable Physicochemical Properties: Its properties can be adjusted by changing parameters such as composition, molecular structure, and degree of polymerization to meet different application requirements.
Production Process
There are mainly two production processes, the batch method and the continuous method. The continuous method has high production efficiency, high product conversion rate, few side - reactions, low production cost, and stable product performance, but the equipment investment is huge, such as the continuous fixed - bed process used by Huntsman. The batch - type process has a small equipment investment, can flexibly switch product types, but has low production efficiency, high cost, and relatively poor product quality.
Application Fields
- High - performance Composites: As a high - performance curing agent for epoxy resins, it is used to produce high - strength and high - toughness composites.
- Polyurea: As a key component of polyurea materials, it is used in the waterproof systems of concrete structures such as high - speed railway bridges and cross - sea bridges.
- Coatings: With low viscosity, when applied to epoxy floor or anti - corrosion coatings, it can reduce the amount of solvents and lower the system viscosity.
- Adhesives: As an epoxy resin curing agent, the cured product has excellent toughness and fatigue resistance, and is widely used in adhesives and structural adhesives.
- Gasoline Detergents: It has excellent cleaning, dispersing, demulsifying, corrosion - inhibiting, and anti - oxidizing properties, and can inhibit the formation of deposits in automobile fuel injectors, intake valves, and combustion chambers.
Packaging and Storage
It is usually packaged in 200 - kg steel drums, 942 - kg IBC drums, or 23000 - kg ISO tanks. It should be stored in a cool and ventilated warehouse, away from direct sunlight. It can be stored at room temperature in the air, and nitrogen - filled storage is recommended to reduce the impact of high temperature and absorb moisture and carbon dioxide in the air.
