Photoinitiator, mainly used in screen printing ink, lithographic printing ink, flexo printing ink, wood coating 

3 .storage  for   Photoinitiator TPO
 ventilated warehouse; keep away from sunshine; avoid fire; avoid moisture.

Application:
It is widely used in various coatings. Because of its excellent absorption performance, it is especially suitable for silk screen printing ink, lithography printing, flexographic printing ink and wood coating. No yellowing of the coating, low post polymerization effect and no residue. It can also be used for transparent coating, especially for products with low odor requirements. When used alone in unsaturated polyester containing styrene system, it has high initiation efficiency. Acrylate systems, especially colored systems, usually need to be used in combination with amine, and mixed with other photoinitiators to achieve complete curing of the system, especially for low yellowing, white systems and thick films. The photoinitiator TPO can be used together with MOB240 or CBP393 to improve the curing efficiency. It is the best extraction solvent for petroleum aromatics unit and also used as formylation reagent in fine chemical industry.
