Sinocure® 819 DW Function & Applications:

1. Sinocure® 819 DW has been tested and can be used in printing inks, adhesives, and UV-curable varnishes and paints on wood, paper, metal, plastic and optical fiber surfaces.

2. Sinocure® 819 DW is a dispersion of Sinocure 819 in water,specially used in water-based systems. It is easy to mix into water-based systems and form a stable dispersion.

3. In white paints, colored paints and inks containing titanium dioxide or other pigments with high hiding power, adding a small amount of Sinocure 819 DW can make the coating have excellent curing effects and UV yellowing resistance. Because Sinocure 819 DW has excellent absorption properties, it can be used in thick film systems.

4. Sinocure 819 DW can be mixed with other photoinitiators, such as Sinocure 500 and Sinocure 1173.

5. Since it also absorbs in the long wave band, Sinocure 819 DW can be used in conjunction with UV absorbers, such as Sinosorb 1130, so Sinocure 819 can be used in UV curing coatings that require weather resistance.
