TPO-L is a highly efficient free radical (I) type liquid photoinitiator used primarily for UV curing of corresponding resins such as unsaturated acrylates.
It is especially used in white systems and film thickness UV curing, a very fast curing photoinitiator.
TPO-L is a liquid photoinitiator suitable for use in low yellowing, low odor formulations.
Because TPO-L has a wide range of absorption, it can also be used for curing with white coatings.
In order to improve the surface curing effect, TPO-L is often used together with other photoinitiators, and the recommended concentration of TPO-L is 0.3-5%.
Package: 25kg/drum, can also be designed according to customer requirements.
