中固化学® 819 DW is a dispersion of 中固化学 819 in water,specially used in water-based systems. It is easy to mix into water-based systems and form a stable dispersion.
In white paints, colored paints and inks containing titanium dioxide or other pigments with high hiding power, adding a small amount of 中固化学 819 DW can make the coating have excellent curing effects and UV yellowing resistance. Because 中固化学 819 DW has excellent absorption properties, it can be used in thick film systems.
中固化学 819 DW can be mixed with other photoinitiators, such as 中固化学 500 and 中固化学 1173.
Since it also absorbs in the long wave band, 中固化学 819 DW can be used in conjunction with UV absorbers, such as Sinosorb 1130, so 中固化学 819 can be used in UV curing coatings that require weather resistance.
