EBECRYL® 860

Formulations containing EBECRYL® 860 are characterized by:

• Improved flow and leveling
• Good pigment wetting
• Good substrate wetting
• Good hydrophilic-lipophilic balance for lithography

UV/EB cured products based on EBECRYL 860 are characterized by the following performance properties:

• Enhanced adhesion on paper and metal
• Good surface appearance
• Improved substrate wetting
• Good pigment wetting

The actual properties of UV/EB cured products also depend on the selection of other formulation components such as reactive diluents, additives and photoinitiators.

Formulated UV/EB curable products containing EBECRYL® 860 may be applied via direct or reverse roll, offset gravure, metering rod, slot die, knife over roll, air knife, curtain, immersion and spin coating methods, as well as flexographic, lithographic and screen printing.

EBECRYL® 860 is recommended as a modifying resin for:

• Overprint varnishes for paper
• Lithographic ink vehicles
• Metal decorating and protective coatings
• Screen ink vehicles
• Pigmented coatings for wood

EBECRYL® 860 - Viscosity vs. Temperature:

• Graph illustrates the change in viscosity of EBECRYL® 860 with increasing temperature.

EBECRYL® 860 - Viscosity Reduction With Reactive Diluents:

Viscosity Reduction: 

• Graph shows the viscosity reduction of EBECRYL® 860 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.

• Avoid contact with eyes and skin. Direct contact with this material may cause moderate eye and mild skin irritation.
• Contact with skin may cause a crossallergic reaction in persons already sensitized to acrylate materials. Wash thoroughly after handling.
• Keep container tightly closed. Use with adequate ventilation.

• The recommended storage temperature range for EBECRYL® 860 is 4°C to 40°C (39°F to 104°F).
• 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.
