EBECRYL® 4857

EBECRYL® 4857 is a low viscosity, monomer free aliphatic urethane diacrylate which exhibits good flexibility in UV or EB cured films. The resin is designed to exhibit low yellowing and good exterior durability. Due to its low Tg the product is suitable for applications requiring haptic properties (e.g. “soft touch/feel”).

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.
