EBECRYL® 250

EBECRYL® 250 is an undiluted high molecular weight aliphatic urethane diacrylate resin, characterized by its light color and lower viscosity. Films of EBECRYL® 250 cured by exposure to ultraviolet light (UV), electron beam (EB) or by means of peroxide are soft and flexible, exhibiting the inherent non-yellowing properties typical of an aliphatic urethane. This resin is most often used as an additive to improve the flexibility of finished formulations.

Performance Highlights

EBECRYL®® 250 is characterized by:

  • Light color
  • Relative low viscosity

UV/EB cured products based on EBECRYL®® 250 are characterized by the following performance properties:

  • Improved flexibility
  • Non-yellowing

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

Technical Details & Test Data

Viscosity Reduction
  • EBECRYL® 250 can be diluted with reactive monomers such as 1,6- hexanediol diacrylate (HDDA) and isobornyl acrylate (IBOA), methyl methacrylate (MMA), hydroxypropyl methacrylate (HPMA) and isobornylmethacrylate (IBOMA).
  • The specific reactive diluent(s) used will influence performance properties such as hardness and flexibility. HDDA and IBOA are produced by allnex

Storage & Handling

Storage and Handling Conditions
  • Care should be taken not to expose radiation curable products to temperatures exceeding 40°C for prolonged periods or to direct sunlight.
  • This might cause uncontrollable polymerization of the product with generation of heat.
  • Storage and handling should be in stainless steel, amber glass, amber polyethylene or baked phenolic lined containers.
  • Do not store this material under an oxygen free atmosphere. Use dry air to displace material removed from the container.
  • EBECRYL® 250 should not be stored for more than 2 years.
