EBECRYL® 4858

EBECRYL® 4858 is a low viscosity aliphatic urethane diacrylate. Due to a low intrinsic viscosity, EBECRYL® 4858 offers ease of formulating in energy curable systems that are low in viscosity with high oligomer content. Films of EBECRYL® 4858 cured by ultraviolet light (UV) or electron beam (EB) exhibit good hardness, optically clarity, low color and good impact resistance.

Viscosity Reduction

GRAPH I:EBECRYL®4858 - VISCOSITY REDUCTION WITH REACTIVE DILUENTS

EBECRYL®4858 - Viscosity Reduction - 1

 

GRAPH II:EBECRYL®4858 - VISCOSITY VS. TEMPERATURE

EBECRYL®4858 - Viscosity Reduction - 1

  • Graph I shows the viscosity reduction of EBECRYL®4858 with 1,6-hexanediol diacrylate (HDDA)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®4858 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.
