Description
LAP is lithium phenyl(2,4,6-trimethylbenzoyl)phosphinate (CAS 85073-19-4), a water-soluble photoinitiator for free-radical polymerization. Its molecular formula is C16H16LiO3P.
LAP has been studied for polymerization at 365 nm and 405 nm in aqueous acrylate systems. These irradiation wavelengths are not the same as an absorption maximum: select the light source, concentration and exposure for the complete formulation.

CAS No: 85073-19-4
Molecular formula: C16H16LiO3P
General information
LAP is a water-soluble photoinitiator for free-radical photopolymerization of suitable aqueous acrylate formulations. The complete formulation and irradiation conditions determine curing response.
Specification:
| Appearance | White powder |
| Purity | ≥98.5% |
| Absorption peak | 371nm |
| Volatile content | ≤0.5% |
Applications and formulation considerations
LAP can initiate polymerization in suitable water-based photocurable inks, resins and hydrogel research formulations. Set concentration and light exposure through formulation trials. Research results obtained with specific cells or materials do not establish biological suitability of the supplied grade.
Package:
1kg/Bag
Storage:
Stored in a cool dry place out of direct sunlight.
Avoid exposing to light and heating.
Protecting the product from leakage, rain and insolation during transportation.
