Performance Highlights

EBECRYL® 3708 is characterized by:

  • Relatively low viscosity
  • Good UV/EB cure response

UV/EB cured products based on EBECRYL® 3708 are characterized by the following performance properties:

  • Good flexibility
  • Good chemical resistance
  • High gloss
  • Toughness
  • High impact resistance

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

EBECRYL® 3708 - Viscosity Reduction With Reactive Diluents:

EBECRYL® 3721

Viscosity Reduction :

  • Graph shows the viscosity reduction of EBECRYL® 3708 with 1,6-hexanediol diacrylate (HDDA), isobornyl acrylate (IBOA), trimethylolpropane triacrylate (TMPTA), and tripropylene glycol diacrylate (TPGDA).
  • Although viscosity reduction can be achieved with non-reactive solvents, reactive diluents are preferred because they are essentially 100 percent converted during UV/EB exposure to form a part of the coating or ink, thus avoiding solvent emissions.
  • The specific reactive diluents used will influence performance properties such as hardness and flexibility.

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.
