EBECRYL® 3415

EBECRYL®® 3415 is characterized by:

• Excellent cure speed
• High gloss
• Good intercoat adhesion
• UV cured products based on EBECRYL® 3415 exhibit excellent adhesion to a variety of plastic substrates including:
• Polycarbonate
• Polystirene
• Polyethylene terephthalate, glycol-modified (PET-G)
• Vinyls – rigid, matte, and glossy
•  Polyvinyl chloride (PVC)

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 products containing EBECRYL® 3415 may be applied via screen methods (flat bed or rotary) and are recommended for use in:

• Screen inks
• Coatings for a variety of plastics

EBECRYL® 3415 is recommended for use in the screen printing industry as an excellent product for plastic applications in the following markets:

• Banner / POP
• Container
• CD
• Loose leaf
• Membranes / Switches

Graph I shows the viscosity reduction of EBECRYL® 3415 with 1,6-hexanediol diacrylate (HDDA), isobornyl acrylate (IBOA)(1), trimethylolpropane triacrylate (TMPTA), trimethylolpropane ethoxy triacrylate (TMPEOTA), 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.
