Products in Bookbinding: Radiation Curable Coating

EBECRYL® 525 is a modified polyester resin expertly diluted with 40% tripropyleneglycol diacrylate. This product is particularly well-suited for applications in laminating adhesives, contributing to effective bonding between materials like paper/aluminum, paper/LDPE, and paper/polypropylene, among others. Additionally, EBECRYL® 525 finds recommendations for use in screen ink vehicles, providing good inter-coat adhesion, and as an adherable primer coating on metals. Its attributes include faster cycle time, low-temperature curing, low energy consumption, and long pot life, making it a good choice for radiation-curable coatings.

Omnicat BL-550 is a liquid photoinitiator blend, based on Omnicat 550 (20%), Propylene Carbonate (25%) and cycloaliphatic epoxy (55%).

Omnicat 445 is a low odor, benzene free iodonium hexafluorophosphate salt for cationic curing of epoxy, oxetane, and vinyl ether formulations.

Omnicat 432 is a mixture of triarylsulfonium hexafluorophosphate salts and propylene carbonate, for cationic curing of epoxy, oxetane, and vinyl ether formulations.

Omnicat 550 is a highly reactive odorless and benzene free photoinitiator designed for use in cationic curing inks and coatings. It is particularly suited to use in pigmented inks. Omnicat 550 has good solubility in the cycloaliphatic epoxides and oxetane diluents used in cationic UV curing formulations. Omnicat 550 is not sensitized by either hydroxyketone photoiniators, thioxanthones or anthracene derivatives.

Omnirad 379 is a highly efficient UV-curing agent used to initiate the photo polymerization of unsaturated prepolymers in combination with mono- or multifunctional monomers. Omnirad 379 is especially suitable for pigmented UV-curable systems, photoresists and printing plates. Its excellent solubility (compared to Omnirad 369) makes it easy to incorporate into nearly all formulations.

Omnicat 440 is a low odor, benzene free iodonium hexafluorophosphate salt for cationic curing of epoxy, oxetane, and vinyl ether formulations.

Omnicat 320 is a colorless liquid photoinitiator of mixed triarylsulfonium hexafluoroantimonate salts in propylene carbonate. Omnicat 320 has been designed for the cationic curing of inks and coatings based on epoxy, oxetane, and vinyl ether formulations. Omnicat 320 exhibits high cure-speed, low odor, and excellent post cure.

Omnicat 270 is a photo initiator recommended for the cationic polymerization of formulations based on epoxies or oxetane. Omnicat 270 is a solid of a high-molecular-weight sulfonium salt free of heavy metals. Omnicat 270 develops very low odor during and after curing and shows very low migration properties which makes the product especially suitable for food packaging applications.
