Chemical Structure
Basic Info
TPO Photoinitiator (Trimethylbenzoyl Diphenylphosphine Oxide) is a widely used photoinitiator with the chemical formula C22H21O2P. TPO is an excellent free radical photoinitiator, especially suitable for UV curing systems because it can quickly decompose under ultraviolet (UV) light to generate free radicals, thereby initiating polymerization. This rapid free radical generation property performs well in coatings, inks, and adhesives applications.

Product Packaging
Coatings and inks:
UV-curing coatings: TPO Photoinitiator acts as a photoinitiator in coatings to rapidly initiate resin polymerization and shorten curing time. It is particularly suitable for coatings on wood, plastic, and metal surfaces to enhance their hardness and wear resistance. In addition, due to its low yellowing properties, TPO is an ideal choice for high-transparency coatings.
Printing inks: TPO Photoinitiator is used in UV-curing inks to dry printed patterns quickly, ensuring the clarity and high-quality output of delicate patterns. It is suitable for rapidly producing label printing, packaging, and advertising materials.
Adhesives:
Photocuring adhesives: Among UV-curing adhesives, the TPO Photoinitiator can provide fast and uniform curing and is suitable for bonding electronic components and optical devices in precision manufacturing. TPO’s low yellowing properties ensure that the adhesive layer remains transparent after curing without affecting optical properties.
3D printing:
Photosensitive resins: TPO Photoinitiator is widely used in photosensitive resin materials in 3D printing, especially for SLA and DLP printing technologies. It can cure quickly under UV light, making the interlayer bonding of 3D printing good and improving the finished product’s printing accuracy and surface finish.
Microelectronics packaging:
Packaging materials: In the packaging of semiconductors and electronic components, TPO Photoinitiator is used in UV-cured packaging materials to help form a highly durable protective layer that prevents components from moisture or oxidation and increases product life.
