Performance Highlights

EBECRYL® 8807 is characterized by:
• Moderate viscosity
• Light color
UV/EB cured products based on EBECRYL® 8807 are characterized by the following performance properties:
• Excellent surface cure in air
• Good flexibility and toughness
• Abrasion resistance
• Non-yellowing
The actual properties of UV/EB cured products also depend on the selection of other formulation components such as reactive diluents, additives, and photoinitiators.

Product Applications

Formulated UV/EB curable products containing EBECRYL® 8807 may be applied via direct or reverse roll, offset gravure, metering rod, slot die, knife over roll, air knife, curtain and immersion coating methods.

EBECRYL® 8807 is recommended for use in:

  • Coatings for wood, cement and composite flooring
  • Adhesives or sealants cured with low intensity lamps
  • Flexible coatings requiring rapid cure in air

Table compares the surface cure response of EBECRYL® 8807 with three commercial acrylated aliphatic urethanes.

All were formulated to equal oligomer content. EBECRYL® 8807 requires a significantly lower UV dose to achieve surface cure.

Viscosity vs Percentage Reactive Diluent

EBECRYL® 8807 - Viscosity Reduction With Reactive Diluents:

EBECRYL® 8807

  • Graph shows the viscosity reduction of EBECRYL® 8807 with 1,6-hexanediol diacrylate (HDDA),trimethylolpropane triacrylate (TMPTA), and tripropylene glycol diacrylate (TPGDA). 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, thus reducing solvent emissions.
  • The specific reactive diluents used will influence performance properties such as hardness and flexibility.

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® 8807 may show signs of crystallization.
  • This crystallization can be removed by heating containers of EBECRYL® 8807 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® 8807 does not exhibit signs of crystallization.
