Application
819 has been tested for UV-curing varnish and paint systems, such as wood, paper, metal, plastic, fiber optics,printing inks and prepreg systems.
In opaque white and tinted furniture, the very low added amount of 819 provides excellent cure and yellowing resistance. Moreover, the excellent absorption properties of 819 make it suitable for deep curing.
819 can be used with other photoinitiators for use in glass fiber reinforced materials.
Due to its photosensitivity in the long wavelength band, 819 can be used with UV absorbers.
Storage
Keep in a tightly closed container and store in a cool, dry, dark, ventilated area. Effective from the date of production,within one year.
