EBECRYL® 859

EBECRYL® 859 is a high molecular weight polyester acrylate developed for use in high-speed UV, HUV, UV LED, and EB (electron beam) cured offset lithographic inks. Here's a breakdown of its key characteristics and suggested applications:

Performance Highlights:

• Medium viscosity, making it easy to handle.
• Low odor.
• Excellent pigment wetting, including for carbon black.
• High reactivity.
• Excellent ink water balance.
• Good compatibility with other acrylates.

Performance Properties of UV/EB Offset Lithographic Inks:

• Good flow.
• High gloss.
• Stable ink water emulsion ensuring constant ink transfer.
• Reduced misting.
• Reduced dot gain.
• High cure speed.

It's important to note that the actual properties of UV/EB cured products also depend on other formulation components like reactive diluents, additives, and photo initiators.

Suggested Applications:

• Recommended for commercial applications using high-speed sheetfed offset on paper and board substrates.
• Suitable for other wet or dry offset inks.
• Can be used in UV/EB flexographic and screen inks.

Specifications:

• Acid value: max. 5 mg KOH/g
• Appearance: Clear liquid
• Color, Gardner: max. 15
• Hydroxyl value: max. 20 mg KOH/g
• Residual acrylic acid: max. 500 ppm
• Residual solvent (toluene): max. 10 ppm
• Viscosity at 60°C: 600 - 1200 mPa.s

Precautions:

• Before use, refer to the Safety Data Sheet (SDS) for hazard information, recommended personal protective equipment, and procedures.

Storage and Handling:

• Avoid exposure to high temperatures, direct sunlight, ignition sources, oxidizing agents, alkalis, or acids to prevent uncontrollable polymerization.
• Store and handle in suitable containers (stainless steel, amber glass, amber polyethylene, or baked phenolic lined containers).
• Avoid procedures that remove or displace oxygen from the material.
• Use with adequate ventilation.
• Follow the recommended storage temperature range provided in the SDS.

EBECRYL® 859 offers various benefits for offset lithographic ink applications, including improved performance properties and ease of handling.
