EBECRYL® 8409

EBECRYL® 8409 is a low viscosity aliphatic urethane diacrylate. Films of EBECRYL® 8409 cured by ultraviolet light (UV) or electron beam (EB) exhibit good flexibility, toughness and excellent exterior durability. Low viscosity coatings or enhanced performance via increased oligomer content are possible with EBECRYL® 8409. Note that EBECRYL® 8409 typically develops a semi-crystalline aspect upon storage.

Safety & Health

Safety Precautions
  • Although EBECRYL® 853 is not classified as irritant, it could be used in combination with other components that are eye and skin irritant and have the potential to cause sensitisation or other allergic responses.
  • Therefore appropriate precautions should be taken to avoid eye and skin contact and to avoid inhalation of the aerosols or vapors.

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.
  • Upon storage, EBECRYL® 8409 may show signs of crystallization. This crystallization can be removed by heating containers of EBECRYL® 8409 to a uniform temperature of 60°C.
  • Ovens or hotboxes are recommended methods of heating. Heating tapes should not be used. In typical formulations, EBECRYL® 8409 does not exhibit signs of crystallization.
