- Performance Highlights
EBECRYL® 3721 is characterized by:
- Good UV/EB cure response
UV/EB cured products based on EBECRYL® 3721 are characterized by the following performance properties:
- Increased toughness and impact resistance than standard bisphenol A epoxy acrylates
- Superior chemical resistance
- Good abrasion resistance
- High gloss
The final properties of UV/EB cured products also depend on the selection of other formulation components such as reactive diluents, additives and photo initiators.

Technical Details & Test Data
- Viscosity Reduction
- Viscosity reduction of EBECRYL® 3721 is possible with common reactive diluents such as 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.
