Kimyasal Ürün Fotobaşlatıcısı 819 CAS 162881-26-7 Düşük Fiyat ile

Photoinitiator 819 (Chemical name: Phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide, CAS: 162881-26-7) is a highly efficient Type I free-radical photoinitiator.
As a high-performance acylphosphine oxide photoinitiator, 819 exhibits excellent absorption in the near-UV and visible regions, with an absorption wavelength extending up to 450 nm. Its most outstanding performance advantages include strong deep-curing capability, high photoinitiation efficiency, and excellent yellowing resistance, making it particularly suitable for applications where traditional photoinitiators struggle to achieve deep curing, such as thick film systems, pigmented systems, and white coatings/inks.
