2-Methylbenzothiazolium derivatives as cationic photoreactive crosslinker for acrylic pressure-sensitive adhesives containing oxirane groups from glycidyl methacrylate

Hot-melt pressure-sensitive adhesive for seamless bonding of nylon fabric Part II: Process parameter optimization for seamless bonding of nylon fabric

“…Czech et al 10 presented the cationic UV-crosslinking of an acrylic PSA containing oxirane groups in the structure and with the cationic photoinitiator 1,10-bis[N,N 0 -(2-methylbenzothiazolium)] decane diodide to promote properties such as the tack, peel adhesion, and shear strength of self-adhesive polymer layers. Wu et al 11 grafted the photoinitiator 4-maleimidobenzophenone on styrenic block copolymers as the main constituent and cured it with UV light to make HMPSAs.…”

Photoreactive UV-Crosslinkable Acrylic Pressure-Sensitive Adhesives (PSA) Containing Multifunctional Photoinitiators

“…Through its concentration controls directly both the crosslinking rate and the penetration of the UV radiation, and therefore the cure depth [11][12][13][14][15][16]. The efficiency of radical photoinitiators is dependent on a strong absorbance of the UV-radiation emitted by the UV-lamp, a short lifetime of the excited states to avoid quenching by atmospheric oxygen, a fast photolysis and bleaching, which generate the free radicals, a high reactivity of the free radicals evolved toward the monomer function, a good solubility of the photoinitiator in the formulation and the formation of non-colored and odorless photoproducts [15,[17][18][19][20][21][22]. In the case of saturated acrylic pressure-sensitive adhesives, the photogeneration of initiator radicals by α-cleavage photoinitiators (Ph I ) or H-abstraction photoinitiators (Ph II ) is followed by reaction with the acrylic chain to produce a new radical that reacts with a neighboring acrylic chain [23].…”
