| Chemical Name: | Bis(2,4,6-trimethylbenzoyl)-phenylphosphineoxide | |
| CAS： | 162881-26-7 | |
| Molecular Weight: | 418.4645 | |
| Molecular Formula: | C26H27O3P | |
| Description: | Photoinitiator 819 is a versatile photoinitiator for radical polymerization of unsaturated resins upon UV and near visible light exposure. With the below three advantages, photoinitiator 819 has successfully solved the problems that often frustrate formulators: I. Good performance of curing pigmented formulations and in outdoor applications, it can be formulated with UV absorbers to gain good weather stability, while without harming the cure speed. II.Good through-curing of thick coating film. III.To give a clean white appearance in contrast to the off-white color associated withother long wavelength absorption photoinitiators. |

| Physical Properties: | Items | Standard |
| Appearance | Pale yellow powder | |
| Assay | ≥98.5% | |
| Melting point | 127.0~135.0℃ | |
| Loss on drying | ≤0.2% | |
