Product Name:Ethyl (2,4,6-trimethylbenzoyl)phenylphosphinate
English Name:Ethyl (2,4,6-trimethylbenzoyl)phenylphosphinate
CAS No.:84434-11-7
Aliases:Photoinitiator TPO-L, Ethyl phenyl(2,4,6-trimethylbenzoyl)phosphinate
Molecular Formula:C18H21O3P
Physical Properties:Light yellow transparent liquid. Density: approx. 1.10 g/cm³ at 25 °C. Boiling point: >200 °C (decomposition). Flash point: approx. 110 °C. Easily soluble in organic solvents such as toluene, ethyl acetate, and acetone; slightly soluble in water. Sensitive to UV light, with maximum absorption wavelength at about 380 nm and good photoinitiating activity in the range of 380–420 nm.
Uses:As a highly efficient liquid photoinitiator, it is widely used in UV-curable systems such as UV-curable coatings, inks, adhesives, and 3D printing photosensitive resins. It features excellent solubility, low yellowing, and low migration, making it suitable for high-color systems and deep curing. The recommended dosage is typically 1–5% of the total formulation.
Technical Specifications:
Appearance: light yellow transparent liquid
Content: ≥95%
Density (25°C): approx. 1.10 g/cm³
Viscosity (25°C): approx. 50–150 mPa·s
