Ethyl (2,4,6-trimethylbenzoyl) phenylphosphate (TEPO) is a highly efficient radical (I) liquid photoinitiator, which is mainly used for UV curing of acrylic resin and styrene unsaturated polyester.
TPO-L is used for UV paints with very low yellowing and white pigments;
TPO-L is used for UV screen printing inks, UV offset printing and UV flexo printing inks;
Low odor varnish, paper base paint, lightfast printing plate, stereolithography.
TPO-L is a liquid UV initiator for unsaturated polyesters containing acrylic resins and styrene. Because it is liquid,TPO-L is "easy to add" to all formulations. Because TPO-L absorbs long wavelengths in the UV spectrum, it can also completely cure coatings with titanium dioxide and flat coatings with titanium dioxide. The coatings thus obtained are characterized by extremely low yellowing.
Due to its low volatility,TPO-L is suitable for the production of low-odor formulations. TPO-L is added in a proportion of 0.3-5% and appears as a polymerizable fraction in paints and printing inks.
TPO-L is often combined with other photoinitiators, 184, 1173, TZT or benzophenone. This promotes surface curing. Because TPO-L absorbs long-wavelength UV, it and products containing it are sensitive to sunlight. As a result, it must be stored and handled to exclude light with wavelengths below 500nm (e.g., by covering windows and lamps with yellow film).
