Lencolo 5007D Liquid Deep-cure Photoinitiator TPO
Description
Lencolo 5007D is liquid TPO with a broad absorption range, featuring an effective absorption peak at 240-400 nm and continued absorption up to approximately 420 nm. Its absorption peak is longer than that of conventional photoinitiators. Upon irradiation, it generates both benzoyl and phosphinoyl radicals, each capable of initiating photopolymerization, resulting in fast UV curing. It also exhibits photobleaching properties, making it suitable for thick-film deep curing and non-yellowing coatings. Low volatility makes it suitable for use in water-based systems.

Performance
Liquid TPO exhibits excellent compatibility with various monomers and UV resins, providing convenient use. It is highly suitable for 100% solids UV systems, a wide range of UV ink systems, and UV formulations where adding powdered photoinitiators makes fine-mesh filtration difficult.
Compared with conventional TPO, most properties are similar. While the curing rate is slightly slower, it offers lower yellowing tendency and can be used in water-based UV systems.
Application
This product is mostly used in white systems, and can be used in photocurable coatings, printing inks, UV curing adhesives, optical fiber coatings, photoresists, photopolymerization printing plates, stereolithography resins, composite coating materials, dental fillings, and other related applications.
Usage method:
Recommended addition: 0.5~5%
It is recommended that users determine the optimal dosage through preliminary testing before use.
