Photoinitiator 819 Description
What is Photoinitiator 819 ?
Photoinitiator 819 is a key component of photopolymerization materials and plays a decisive role in the speed of photopolymerization. This substance is more widely used in 3D printing than the photoinitiator TPO and has significant advantages in performance, except in the field of short-term colorless systems. Compared with the photoinitiator TPO, the photoinitiator 819 is more commonly used in 3D printing, equivalent to an enhanced version of TPO.
Photoinitiator 819 can also be used for colored UV cured plastic coatings. UV coatings are 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 is not good after coloring, resulting in poor adhesion of the coating and poor dispersion and arrangement of pigments by UV resin, which seriously affects the appearance of the coating. Therefore, the traditional construction process is to first apply solvent based colored primer for coloring, then apply UV varnish after baking to improve the various physical properties of the coating surface.

Photoinitiator 819 Applications
Photoinitiator 819 is an efficient UV initiator mainly used for the photopolymerization reaction of UV cured materials, and is widely used in fields such as coatings, inks, 3D printing, etc.
Main application areas
Colored UV cured plastic coating: used for the manufacturing of plastic shells for electronic and household appliances, especially suitable for systems containing pigments or titanium dioxide, which can improve the curing effect and UV yellowing resistance of the coating.
Thick film system curing: Due to its excellent light absorption ability, it is suitable for curing thick film coatings on substrates such as wood, metal, and plastic.
White/color paint system: When used in combination with photoinitiator 184, it can enhance the curing efficiency of white or high coverage paint.
3D printing materials: more widely used in 3D printing than photoinitiator TPO, especially suitable for short-term colorless systems
