Log P: –3.95 (25 °C)

pKa (acidic hydrolysis product): 4.24 (20 °C)

Solubility: reacts slowly with water; miscible with common epoxy resins and most organic solvents (acetone, toluene, chloroform, ethyl acetate)

Stability: hygroscopic; sensitive to moisture—sealed, inert atmosphere storage recommended

Main applications

Epoxy curing agent – imparts low colour, low viscosity, fast cure and excellent high-temperature electrical properties; widely used in LED encapsulants, high-voltage coils, electronic potting, printed-circuit laminates and powder coatings.

Intermediate – building block for ester plasticisers, alkyd resins, specialty polyimides and pharmaceutical precursors.

Foundry & composites – employed in resin systems for investment casting and fibre-reinforced composites where low shrinkage and good hot strength are required.

Safety & handling

Classified as a harmful (Xn) and sensitising substance.

Risk phrases: R41 (serious eye damage), R42/43 (respiratory & skin sensitisation).

Recommended protection: wear gloves, goggles and adequate respiratory protection; work under local exhaust ventilation; store under dry inert gas; avoid contact with skin, eyes and clothing.
