HDDA

HDDA is a difunctional reactive diluent that is commonly used as a component of ultraviolet light (UV) and electron beam (EB) curable coatings and inks. HDDA is particularly useful in coatings and inks where improved elasticity, weathering and adhesion are desired in combination with excellent water resistance.

Product Performance

HDDA is characterized by:

  • Very low viscosity
  • Low color
  • Efficient reduction of oligomer viscosity


UV/EB curable formulated products containing HDDA are characterized by:

  • Improved elasticity
  • Improved weathering
  • Good cure response at low cross-link density
  • Improved adhesion
  • Good water resistance


The actual properties of UV/EB cured products also depend on the selection of the other formulation components such as oligomers, additives and photoinitiators.

Storage & Handling

Storage Conditions
  • Care should be taken not to expose the product to high temperature conditions, direct sunlight, ignition sources, oxidizing agents, alkalis or acids. This might cause uncontrollable polymerization of the product with the generation of heat.
  • Storage and handling should be in stainless steel, amber glass, amber polyethylene or baked phenolic lined containers. Procedures that remove or displace oxygen from the material should be avoided.
  • Do not store this material under an oxygen free atmosphere. Dry air is recommended to displace material removed from the container. Wash thoroughly after handling. Keep container tightly closed. Use with adequate ventilation.
