MEHRSTUFIGES BESTRAHLUNGSVERFAHREN ZUR HERSTELLUNG EINES KLEBSTOFFS AUF ACRYLBASIS

摘要

A two-step method of polymerizing a composition containing a free radical photoinitiator includes the sequential steps of exposing the composition to a first radiation source having a maximum spectral output occurring at a wavelength of greater than 300 nm and, thereafter, exposing the composition to a second radiation source having a maximum spectral output occurring at a wavelength of less than 300 nm.
