2-Methyl-4'-(Methylthio)-2-Morpholinopropiophenone is an efficient UV photoinitiator for initiating UV polymerization of unsaturated prepolymer systems, Such as acrylic resins and monofunctional and multifunctional vinyl monomers. The initiator molecule has a certain light absorption capacity in the ultraviolet region (250-400 nm) or the visible region (400-800 nm). After direct or indirect absorption of light energy, the initiator molecules transition from the ground state to the excited singlet state, through intersystem conversion to excited triple state. After undergoing a single molecular or bimolecular chemistry, initiator molecules produce reactive debris that initiates polymerization of the monomers, which may be free radicals, cations, anions, etc. According to the different initiation mechanism, the photoinitiator can be divided into free radical polymerization photoinitiator and cationic photoinitiator, among which the most widely used is free radical polymerization photoinitiator. The characteristic of high absorbency of 2-Methyl-4'-(Methylthio)-2-Morpholinopropiophenone makes it particularly suitable for UV curable inks and colored coatings. UV inks contain a greater amount of photoinitiator, and it is these photoinitiators that promote the rapid drying of the ink during the printing process. These photoinitiators themselves are not stable, even in the dark, and it is also prone to dark reaction, resulting in one by one ink glue nucleus, followed by a large area of retrogradation. Especially in the preservation of metal ink, similar situation occur more often. Therefore, it is recommended that the ink pigment and the binder separately stored. If used, stir and mix the two with a large machine.
Highly efficient photoinitiator can be used in UV curing systems to extend storage with non-yellowing for a long time. It is an initiator specifically for pigmented UV-curable coatings, inks and adhesives colored solidification system, and it could be used with184, ITX and other initiators. It can be used for colored ink systems, paper/metal and plastic varnish and electronic inks. It is also as a UV absorber for cosmetics and other industries with suggested supplementation of 2-6%. | [Application]
