EBECRYL® 3418

EBECRYL® 3418 is a modified bisphenol A epoxy diacrylate that exhibits excellent reactivity and reduced viscosity. Films of EBECRYL® 3418 cured by ultraviolet light (UV) or electron beam (EB) demonstrate high flexibility, gloss, toughness, adhesion and superior chemical and scratch resistance.

Technical Details & Test Data

Technical Data

Viscosity Reduction

  • EBECRYL® 3418 can be combined with reactive diluents such as dipropylene glycol diacrylate (DPGDA)  1,6-hexanediol diacrylate (HDDA)(1), isobornyl acrylate (IBOA), and trimethylolpropane triacrylate (TMPTA).
  • 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.
Stress-strain Properties

Graph I compares the stress-strain curves of UV cured free films of EBECRYL® 3418 with the modified bisphenol A epoxy epoxy acylate oligomers, EBECRYL® 3500 and EBECRYL® 3708. For proper comparison, the EBECRYL® 3500 and EBECRYL 3708 were combined with 35% by weight DPGDA.

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.
