Tpo-L CAS 84434-11-7 fábrica de bajo precio de alta calidad

Photoinitiator TPO-L (Chemical name: Ethyl (2,4,6-trimethylbenzoyl) phenylphosphinate, CAS: 84434-11-7) is a highly efficient Type I liquid photoinitiator.
As a high-performance acylphosphine oxide photoinitiator, TPO-L exhibits excellent absorption in the long-wave UV and near-visible region (absorption peak ~370 nm), making it particularly suitable for UV-LED curing systems. Its key advantages include strong deep-curing capability, low yellowing, and low odor, making it ideal for white systems, thick film systems, and coatings/inks with stringent color requirements.
