Light shielding phenomenon of photoinitiator & two-photon photoinitiator Due to the absorption and reflection of the pigment, the local ultraviolet light is shielded, so that the photoinitiator can not effectively absorb the light rays, and the curing conjunctiva rate of the ink is greatly reduced or the cured conjunctiva does not occur. The problem of [...]

Induction of photoinitiator In the photocuring system, UV adhesive, UV coating and UV ink undergo chemical change by accepting or absorbing external energy, and decompose into free radicals or cations, thereby initiating polymerization reaction. The substances that generate radicals and further initiate polymerization by light irradiation are collectively called photoinitiators. After irradiation, some monomers absorb [...]
Introduction of polytetramethylene ether glycol (PTMEG) Polytetramethylene ether glycol (PTMEG) is homopolymer obtained by cationic ring opening polymerization of monomer tetrahydrofuran (THF) in the presence of catalyst.
