Recent Developments in Radical Photoinitiator Chemistry

Radiation curing is an established technology used in many industrial manufacturing processes.New applications and technical specifications stimulate the continuous Measuring Spoon Sets development of tailor-made photoinitiators which can efficiently meet specific requirements.A new class of radical photoinitiators, bisacylphosphine oxides (BAPO), give four initiating radicals per photoinitiator molecule and undergo photo-bleaching 27” Double Wall Oven of the low-energy absorption band.These features make the compounds highly efficient for radiation curing of highly opaque white pigmented systems, thick coatings, or fiber-reinforced formulations.
