Photoinitiator 184 for UV radiation curing systems

Product Introduction
Photoinitiator 184 is the best choice for non-yellowing applications. It is a fragmentation photoinitiator with high speed and long storage life. Non-yellowing and low irritation properties make it ideal for clear coats on paper, flooring, metal, plastic and wood.

Specifications

Application
Photoinitiator 184, when irradiated by ultraviolet light, undergoes intramolecular homolytic fracture to generate a pair of free radicals, which initiates the polymerization of the ultraviolet curing system. It does not require a hydrogen donor to initiate free radicals. But its free radicals are very sensitive to oxygen in the air.
  When non-yellowing characteristics are strictly required, photoinitiator 184 is strongly recommended. The outdoor exposure test results show that it has better long-term non-yellowing performance compared with other initiators. In addition, it is less sensitive to air inhibition than Photoinitiator 1173 during curing.
The usage rate of photoinitiator 184 varies with system composition, light source, line speed and film thickness, but is usually between 0.5% and 5% w/w. Photoinitiator 184 can be used in printing inks, overprint varnishes, wood paints, adhesives and photoresist dry films.

Storage Conditions
Must be stored in an airtight container in dark and dry conditions.
