Photoinitiator TPO-L


Photoinitiator TPO-L is a kind of liquid photoinitiator, which is mainly used in yellowing resistant system. It has excellent yellowing resistance, low mobility and low odor. It is especially suitable for UV curing with white system and thick film, and the curing speed is very fast. It is suitable for formulation systems with low yellowing and low odor. The following are the product pictures and technical parameters of photoinitiator TPO-L:

TPO-L shows good solubility in some common UV formulations, such as acrylate and unsaturated polyester system. Because TPO-L has a wide range of absorption, it can also be used for curing with white paint. In order to improve the curing effect of the surface, TPO-L is often used in combination with other photoinitiators, such as 184pj1173 and α-hydroxy ketones. At the same time, TPO-L is a liquid UV initiator for unsaturated polyester containing acrylic resin and styrene. Because of its low volatilization rate, TPO-L is suitable for the production of low-odor formulations. The polymerizable part of the product can be applied to paints and printing inks by adding TPO-L at the proportion of 0.3%.
