Phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide Usage:  Phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide is a useful research chemical compound. Versatile UV photoinitiator for radical polymerization of unsaturated resins, especially pigmented formulations. Photoinitiator 819 (HRcure-819) can also be used in colored UV-curable plastic coatings.   UV coatings have been widely used on plastic shells of various electronic and household appliances due to their excellent performance and efficient production.   However, the deep curing of UV coatings after coloring is not good, resulting in poor film adhesion and poor dispersion and arrangement of pigments by UV resins, which seriously affect the appearance of the coatings.   Therefore, the traditional construction process is to paint solvent-based colored primer first;   after baking, apply UV varnish to improve the physical properties of the film surface.

We have a professional export team and our brushes are exported to European and American countries. We can do OEM and ODM services. We have a brush design team that develops and designs new brushes every year.
