Product Parameters
Photoinitiator TPO More Details:
Brief: Photoinitiator TPO is a kind of highly efficient free radical (1) type photoinitiator with absorption in the long wavelength range.Because of the wide range of absorption, the effective absorption peak at 350 ~ 400 nm, soaking up to about 420 nm, its absorption peak Chemicalbook weaker than conventional initiator is long, light can generate benzoyl and phosphoryl two free radicals, can cause aggregation, so the light curing speed, it also has light bleaching, suitable for the characteristics of deep thick film and coating curing the same yellow, with low volatile, suitable for water-based.

Photoinitiator TPO Usage:
- As Photoinitiator, it mainly used in white system, UV curing coatings, printing inks, UV curing adhesives, photoconductive fiber coatings, photoresist, photopolymeric plates, stereoscopic lithography resins, composite materials, dental fillers, etc.
- TPO is fully cured on either white or high titanium dioxide pigmented surfaces.Widely used in a variety of coatings, due to its excellent absorption properties, it is especially suitable for screen printing ink, lithography printing ink, flexo printing ink, wood coating.It can also be used for transparent coatings, especially for products with low odor requirements.
- It is the best extraction solvent for petroleum aromatics unit and also used as formylation reagent in fine chemical industry.
