Category: Polyether amine curing agent, industrial organic synthetic raw material, polymer additive
2. Physical and Chemical Properties
Physical Properties
- Appearance: Colorless to light yellow transparent viscous liquid
- Odor: Mild characteristic amine odor
- Solubility: Miscible with ethanol, acetone, toluene, water; insoluble in aliphatic mineral oil
- Melting Point: Varies with molecular weight, D230: -60 ℃
- Boiling Point: Decompose at high temperature
- Refractive Index nD20: 1.440–1.460
- Density (20℃): 0.94–0.98 g/cm3
- Flash Point: ≥110 ℃
- Hygroscopy: Slightly hygroscopic
- Aqueous property: Weak alkaline aqueous solution, stable under neutral and weak alkaline environment
Chemical Properties
- Molecular structure: Polypropylene glycol main chain with terminal primary amino groups, flexible long polyether segment
- Curing reaction: Amino group crosslinks with epoxy resin to form high toughness epoxy coating and adhesive
- Polyurea synthesis: Reacts with isocyanate to prepare spray polyurea waterproof, wear-resistant elastomer
- Thermal stability: Stable below 120 ℃; long-term high temperature will lead to amine volatilization and viscosity change
- Photostability: Slightly sensitive to strong UV light, long-term irradiation turns pale yellow
- Compatibility: Compatible with epoxy resin, polyurethane, most polar organic solvents; incompatible with strong acid, anionic surfactants
3. Main Application Fields
- Epoxy curing agent (Core Application): For epoxy floor, anti-corrosion coating, structural adhesive, electronic potting glue
- Spray polyurea raw material: Bridge, tunnel, roof waterproof, wear-resistant protective coating
- Industrial additives: Gasoline detergent dispersant, oil field corrosion inhibitor, textile antistatic agent
- Composite materials: RIM reaction injection molding, handicraft resin, carbon fiber composite modifier

Safety Warning
Weak alkaline irritant viscous liquid. Vapor irritates eyes, respiratory tract and skin; long-term skin contact causes dry itching and slight corrosion. All operations must be carried out in ventilated fume hood with dust-proof respirator and nitrile chemical-resistant gloves. Strictly avoid mixing with strong acid to prevent heat release and splashing. Waste liquid shall be neutralized with dilute acid before discharge; residual materials shall be treated as hazardous chemical waste by licensed professional institutions.
