EBECRYL® 600

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.

Specifications:

• 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.
