Product information

WPBG-300 is an ionic photo base generator which can be used for a variety of applications. It shows a high preservation stability in the monomer and indicates a photosensitivity in the long wavelength region by using various sensitizers together.

In photo polymerization processes such as UV and near UV photocure, WPBG products are not subject to inhibition by the oxygen in the air like photo radical generators. They are less likely to cause corrosion problems and the denaturation of cured films like photo acid generators.

The photo generators of the WPBG series generate bases of various basicity, which provide different curing speed and photo-sensitivity. Various grades of WPBG products from high quality, high purity (HP) to general-purpose grades are available.
