- Performance Highlights
EBECRYL® 838 is characterized by:
- Fast cure response
- Moderate viscosity
UV/EB cured products containing EBECRYL 838 are characterized by the following performance properties:
- Good abrasion/scratch resistance
- High surface hardness
- Solvent resistance
The actual properties of UV/EB cured products also depend on the selection of other formulation components such as reactive diluents, additives and photoinitiators.

EBECRYL® 838 - Viscosity Reduction With Reactive Diluents
Graph I shows the viscosity reduction of EBECRYL® 838 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.
