EBECRYL® 898

EBECRYL® 898 is characterized by:

• Extends matting effect
• Low viscosity
• Low odor
• Fast cure

UV/EB cured products based on EBECRYL® 898 are characterized by the following performance properties:

• Provides an outstanding matte effect
• Toughness and adhesion
• High surface hardness

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

Formulated UV/EB curable products containing EBECRYL® 898 may be applied by lithographic, screen, gravure, direct or reverse roll coating and spray methods.
EBECRYL® 898 is recommended for use in matte formulations:

• Wood finishes
• PVC flooring
• Plastic films
• OPVs for paper and plastic

Viscosity reduction of EBECRYL® 898 is possible with common reactive diluents such as dipropyleneglycol diacrylate (DPGDA) 1,6-hexanediol diacrylate (HDDA), octyl/decyl acrylate (ODA-N) 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.

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.
