EBECRYL® 3730-TP25

EBECRYL® 3730-TP25 is the modified diacrylate ester of a bisphenol A based epoxy resin diluted 25% by weight with the reactive diluent tripropylene glycol diacrylate (TPGDA)(1). It is designed primarily for use in ultraviolet light (UV) or electron beam (EB) curable formulations. EBECRYL® 3730-TP25 is light in color with high UV/EB reactivity, and exhibits good wetting of pigments, matting agents and substrates compared to unmodified epoxy acrylates. Cured films based on EBECRYL® 3730-TP25 will typically demonstrate high gloss and hardness, and good chemical resistance.

EBECRYL® 3730-TP25 - Viscosity Reduction With Reactive Diluents

EBECRYL® 3730-TP25 - Technical Data - 1

Graph I shows the viscosity reduction of ebecryl 3730-tp25 with 1,6-hexanediol diacrylate (hdda), isobornyl acrylate (iboa), 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 or ink, 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.
