What Is HDO (1,6-Hexanediol)?
1,6-Hexanediol (HDO) is an aliphatic diol containing two hydroxyl (–OH) groups.
It is a colorless liquid with a mild odor and is widely used as a chemical intermediate in polymer and resin production.
What Is HDO Used For?
1. Polyester & Polyurethane Production
Used in the manufacture of:
- Polyester resins
- Polyurethanes (PU)
- Elastomers
to provide flexibility, strength, and chemical resistance.
2. Acrylate & Methacrylate Derivatives
Serves as a raw material for:
- Hexanediol diacrylate (HDDA)
- UV-curable monomers and oligomers
3. Paints & Coatings
Improves:
- Film durability
- Water and chemical resistance
- Crack resistance
4. Adhesives & Sealants
Enhances:
- Adhesion strength
- Elasticity
- Long-term stability
5. Polymer Modifier & Chemical Intermediate
- Controls molecular weight
- Regulates polymer chain structure
- Used in specialty chemical synthesis
Purposes of HDO
- To improve mechanical properties of polymers
- To provide flexibility and elasticity
- To increase chemical and water resistance
- To enhance performance of coatings and adhesives
- To act as a building block in chemical synthesis
Industries That Use HDO
