EBECRYL® 8315

EBECRYL® 8315 is an aliphatic urethane tetraacrylate diluted with the reactive diluent hydroxypropyl methacrylate (HPMA). Films of EBECRYL® 8315 cured by ultraviolet light (UV) or electron beam (EB) have a unique combination of hardness, toughness, flexibility, and abrasion resistance coupled with outstanding exterior durability properties. These performance properties make EBECRYL® 8315 ideal for applications such as paint protection, printed electronics, automotive interior film and embossing or thermoforming after cure.

Technical Details & Test Data

Viscosity Reduction

Graph I shows the viscosity reduction of EBECRYL® 8315 with 1,6-hexanediol diacrylate (HDDA), 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 reducing solvent emissions. The specific reactive diluents used will influence performance properties such as hardness and flexibility.

Storage & Handling

Storage and Handling 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.
