EBECRYL® 600 is an epoxy acrylate oligomer used primarily in UV/EB (ultraviolet/electron beam) applications, including coatings, inks, and overprint varnishes. Here are the key details about EBECRYL® 600:
Product Description:
- EBECRYL® 600 is a diacrylate ester of a bisphenol A epoxy resin.
- It exhibits a light color and fast cure response.
- Films cured via exposure to UV or EB possess high surface hardness, gloss, and excellent chemical resistance.
Performance Highlights:
- Light color.
- Fast cure response.
- High surface hardness, gloss, and chemical resistance in cured products.
Suggested Applications:
- Overprint varnishes.
- Lithographic and screen inks.
- Coatings for paper, paperboard, wood, chipboard, and rigid plastics.
- Paper upgrading.
- Fast cure coatings.
- Laminating adhesives.
- Wood sealers.

- Acid value: max. 2 mg KOH/g.
- Appearance: Clear liquid.
- Color, Gardner: max. 1.
- Epoxy content: max. 0.5%.
- Viscosity at 60°C: 2000 - 4000 mPa.s.
Typical Physical Properties:
- Density at 25°C: 1.17 g/cm³.
- Functionality: 2.
- Oligomer content: 100%.
Typical Cured Properties:
- Tensile strength: 10,000 psi (67 MPa).
- Elongation at break: 4%.
- Young's modulus: 320,000 psi (2200 MPa).
- Glass transition temperature: 130°C.
Viscosity Reduction:
- Reactive diluents such as 1,6-hexanediol diacrylate (HDDA), isobornyl acrylate (IBOA), trimethylolpropane triacrylate (TMPTA), and tripropylene glycol diacrylate (TPGDA) can reduce the viscosity of EBECRYL® 600.
- Viscosity reduction with reactive diluents is preferred due to their 100% conversion during UV/EB exposure, reducing solvent emissions.
Precautions:
- Follow safety guidelines outlined in the Safety Data Sheet (SDS).
- Avoid exposure to high temperatures, direct sunlight, ignition sources, oxidizing agents, alkalis, or acids.
- Store and handle in appropriate containers with adequate ventilation.
- Use dry air to displace material removed from the container.
In summary, EBECRYL® 600 offers fast curing and excellent performance properties, making it suitable for various UV/EB applications, particularly in coatings and printing inks. Proper handling and storage procedures are essential to maintain its effectiveness and safety.
