Ebecryl 3720-hd20 - Viscosity Reduction With Reactive Diluents

Graph I shows the viscosity reduction of ebecryl 3720-hd20 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.

EBECRYL® 3720-HD20 -Viscosity vs. Temperature

• 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.
