EBECRYL® 8606

EBECRYL® 8606 is an aliphatic urethane tetraacrylate. Films of EBECRYL® 8606 cured by ultraviolet light (UV) or electron beam (EB) have a unique combination of hardness, toughness, flexibility, and abrasion resistance coupled with outstanding exterior durability properties. These performance properties make EBECRYL® 8606 ideal for applications such as paint protection, printed electronics, automotive interior film and embossing or thermoforming after cure.

Performance Highlights

EBECRYL® 8606 is characterized by:

  • Light color
  • Low odor

UV/EB cured products containing EBECRYL® 8606 are characterized by the following performance properties:

  • Outstanding toughness
  • Excellent abrasion resistance
  • Excellent weatherability
  • Thermoformable after cure (small to medium draws)
  • Flexibility
  • Good adhesion
  • Non-yellowing

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

EBECRYL® 8606 - Viscosity Reduction - 1

 

GRAPH II:EBECRYL® 8606 - VISCOSITY VS. TEMPERATURE

EBECRYL® 8606 - Viscosity Reduction - 1

 

  • Graph I shows the viscosity reduction of EBECRYL® 8606 with 1,6- hexanediol diacrylate (HDDA)¹ , hydroxypropyl methacrylate (HPMA)¹ , isobornyl acrylate (IBOA)¹ and trimethylolpropane triacrylate (TMPTA)¹ .
  • 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 reducing solvent emissions.
  • The specific reactive diluents used will influence performance properties such as hardness and flexibility.
  • Graph II illustrates the change in viscosity of EBECRYL® 8606 with increasing temperature.

Storage & Handling

Storage and Handling 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.
