UV-curing is one of the most rapidly growing technologies for inks, printing and packaging. UV-curing systems have been used to dramatically increase line speeds and develop environmentally friendly technology.
The photoinitiator is a key component of an energy curable formulation, as it largely determines the spectral sensitivity and cure response of the system. BTC offers a broad range of highly effective Irgacure® photoinitiators for energy curable inks and overprint varnishes. Energy cured inks and overprint varnishes provide performance attributes such as excellent solubility in acrylate monomers, low yellowing, low odor/low migration, surface cure and through cure properties.
Irgacure® photoinitiators are used for UV-curable inks and printing and for pigmented and energy-curable coatings in combination with clear-coat light.
