Triethylenediamine丨CAS 280-57-9

1. Catalyst in Polyurethane (PU) Production

TEDA is a key tertiary amine catalyst used extensively in the manufacture of polyurethane foams:

Flexible foams: for furniture, mattresses, automotive seating

Rigid foams: for insulation materials in construction and refrigeration

It promotes urethane (gel) and urea (blowing) reactions, ensuring proper foam structure, reactivity, and processing time.

2. Crosslinking Agent and Additive in Coatings

Used as a curing accelerator in epoxy resins and coatings

Enhances film hardness, adhesion, and drying speed

Acts as a crosslinking promoter in high-performance paints and coatings

3. Pharmaceutical Intermediate

Employed in the synthesis of pharmaceuticals and fine chemicals:

Building block in heterocyclic compounds

Reactant in synthesis of antibiotics, fungicides, and other bioactive agents

4. Corrosion Inhibitor

Sometimes used as an additive in metalworking fluids and cooling systems to prevent corrosion and scaling

5. Gas Treatment and CO₂ Capture Research

Studied as a potential sorbent or promoter in advanced CO₂ capture technologies, especially in amine-based gas scrubbing systems

✅ Highly Efficient Catalyst

TEDA is known for its strong catalytic activity, enabling faster and more controlled PU foam reactions with lower usage levels compared to other amines.

✅ Thermal Stability

TEDA has excellent thermal resistance, making it suitable for high-temperature processing in foam and resin systems.

✅ Versatile Compatibility

Works well in a variety of formulations and polymer systems, including polyether and polyester-based PUs, epoxies, and thermoplastics.

✅ Enhanced Foam Quality

Helps improve foam uniformity, cell structure, compressive strength, and dimensional stability, particularly in rigid foams used for thermal insulation.

✅ Low Volatility

Compared to some other tertiary amines, TEDA offers relatively low odor and emissions, supporting low-VOC formulations in modern manufacturing.
