In photo polymerization techniques, photo base generators are not subject to inhibition by oxygen in the air like photo radical generators. WPBG are less likely to cause corrosion problems and the denaturation of cured films like photo acid generators.
Wako launched a number of WPBG series starting with photo base generators WPBG-018, 140, etc, and they are used in a variety of applications.
We can supply various grades of WPBG products from high quality to general purpose same as photo acid generators, please contact us.
(We have a joint development with associate professor Arimitsu of Faculty of Science and Technology in Tokyo University of Science.)
