Photoinitiator TPO, also known as 2,4,6-trimethylbenzoyl-diphenyl-phosphine oxide, is a highly effective photoinitiator that is commonly used in UV-curable systems. It is known for its ability to initiate polymerization when exposed to UV light, leading to the rapid curing of coatings and inks.

How does Photoinitiator TPO work?

When Photoinitiator TPO is exposed to UV light, it undergoes a photolysis process where it breaks down into free radicals. These free radicals then interact with monomers and oligomers in the system, initiating the polymerization reaction. This rapid polymerization process allows for quick curing of the coating or ink, resulting in a durable and high-quality finish.

What are the benefits of using Photoinitiator TPO?

• Rapid curing: Photoinitiator TPO allows for fast curing times, increasing productivity and efficiency in manufacturing processes.
• High reactivity: TPO is known for its high reactivity, ensuring thorough curing of the coating or ink.
• Good compatibility: Photoinitiator TPO is compatible with a wide range of monomers and oligomers, making it versatile for use in various formulations.
