EBECRYL® 444

EBECRYL® 444 is a reactive chlorinated polyester resin diluted 40% with the reactive diluent propoxylated glycerol triacrylate (OTA-480) (1). EBECRYL® 444 is not based on bisphenol A raw materials, and is tin-free. It exhibits good lithographic behavior and pigment wetting properties, and fast cure response in ultraviolet light (UV) curable coatings and inks. Cured films of EBECRYL® 444 display good adhesion to metals, and paper.

Technical Details & Test Data

Viscosity Reduction
  • EBECRYL® 444 can be further diluted with OTA-480 or other reactive monomers such as, 1,6-hexanediol diacrylate (HDDA), tripropylene glycol diacrylate (TPGDA) or 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.
