Application: TPO is a highly efficient free radical type I photoinitiator used primarily for UV polymerization of the corresponding resins. Particularly suitable for low yellowing, white system and thick film curing and resin deep curing, UV curable coating, screen printing ink, lithographic ink, flexo ink, wood coating, printing ink, UV curing adhesive , optical fiber coatings, etc.

Storage and transportation: keep sealed; store under low temperature and dry conditions.
Photoinitiator TPO Application Recommendations: Printing inks and adhesives that have been tested for wood, metal, plastic, paper and fiber surfaces. TPO exhibits good solubility in some common UV formulations such as acrylates, unsaturated polyester systems. It can be used alone or in combination with other photoinitiators, such as alpha-hydroxyketones.
 Recommended dosage: 1 – 5 % photoinitiator TPO
