Products in Electronics Adhesives: Photoinitiator

Esacure ONE is a difunctional alpha-hydroxy ketone photoinitiator. It is a highly reactive difunctional photoinitiator particularly suitable for clear systems. Due to its molecular structure it is particularly suitable for all systems where low VOC, low migration and low extraction values are needed (food packaging).

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.

Omnirad 127 D is a highly efficient Type I Photoinitiator that may be used to initiate the photo polymerization of unsaturated pre-polymers like acrylates – in combination with mono- or multifunctional monomers. Omnirad 127 D is especially suitable for all types of pigmented UV inks (offset, screen, flexo and inkjet) and clear coatings, particularly in thin coatings (such as overprint varnishes) but also in a variety of coating applications.

Omnirad 73 is a highly efficient, low yellowing, Type I photoinitiator used to initiate radical polymerization of unsaturated oligomers e.g. acrylates, after exposure to UV light. It can be used in combination with mono or multi functional monomers as reactive diluents.

Omnirad 2100 is a highly efficient liquid curing agent to initiate radical polymerization of unsaturated resins after exposure to UV light such as those based on a prepolymer – e.g., acrylates and unsaturated polyesters – in combination with mono- or multifunctional monomers as reactive thinners. It is well suitable for formulations in which Omnirad TPO is used. Omnirad 2100 provides all the handling advantages of a liquid product. In thicker coatings Omnirad 2100 offers improved bottom curing compared with that of Omnirad TPO. It is especially suitable for white-pigmented formulations with minimal yellowing after curing and for coatings with low pigment volume concentration. Therefore Omnirad 2100 can be offered in almost all applications as a one-to-one replacement for Omnirad TPO with certain advantages.

Omnirad 184 is a highly efficient non-yellowing photoinitiator used to initiate the photo polymerization of chemically unsaturated prepolymers – e.g., acrylates – in combination with mono- or multifunctional vinyl monomers.

Omnirad 369 is a highly efficient UV-curing agent used to initiate the photo polymerization of chemically unsaturated prepolymers – e.g., acrylates – in combination with mono- or multifunctional monomers.

Esacure 1187 is a modified sulphonium salt hexafluorophosphate diluted in 25% propylene carbonate, which does not release any benzene upon cure.
