Products in Tapes, Labels & Adhesives: Photoinitiator

PL-150 is oligo [ 2-hydroxy-2-methyl-1-[ 4-(1-methylvinyl) phenyl] propanone] and 2-Hydroxy-2-methyl-1-phenyl-1-propanone. It is a very fast curing type-I photoinitiator soluble in most monomers, oligomers and pre-polymers but insoluble in H2O.

Chivacure® 300 is an oligomeric photoinitiator featuring transparent, ultrathin, non-yellowing, and non-migration properties. Equipped with a special “multi-warhead” structure, Chivacure® 300 is highly resistant to oxygen inhibition and can retain sufficient free radicals to initiate the UV curing reaction. Therefore Chivacure® 300 is particularly suitable for applications requiring ultrathin transparent coatings that are less than 5 μm thick (e.g., food or cigarette packaging, adhesive tapes, scratch-resistant glass and metal coatings).

Omnicat 250 is a versatile photoinitiator for cationic polymerization of epoxy- or oxetane-based photocurable systems upon light exposure. It can be used to effectively cure cationic inks and coatings, e.g., printing inks, white base coatings and adhesives. Omnicat 250 is especially suitable to the cure thick and highly pigmented systems.

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

PL-100 is a 70:30 blend of oligo [ 2-hydroxy-2-methyl-1-[ 4-(1-methylvinyl) phenyl] propanone] and 2-Hydroxy-2-methyl-1-phenyl-1-propanone. It is a fast curing type-I photoinitiator soluble in most monomers, oligomers and pre-polymers but insoluble in H2O.

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.

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.

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