TR-1173 is a high-efficiency liquid free radical photoinitiator, which has the following characteristics: high initiation activity, good curing effect, excellent anti-yellowing performance, and good anti-yellowing effect. Used to initiate the polymerization of unsaturated resins and monomers. TR-1173 can be used for acrylate-based UV-curable clear coatings on paper, metal and plastic surfaces, and is recommended for UV-curable coatings that require long-term sun exposure and require little yellowing.

TR-TPO-L is an efficient UV photoinitiator with high initiation activity, excellent solubility and photobleaching performance, and is suitable for systems with high requirements for chroma reduction. TR-TPO-L can be used in formulation systems with low yellowing and low odor. TR-TPO-L is widely used in UV coatings, inks and adhesives.

Under UV illumination, THM202 undergoes both free radical polymerization and cationic polymerization simultaneously during the curing process, resulting in the formation of an interpenetrating polymer network structure. The cured film's mechanical properties, solvent resistance, and thermal stability are superior to those of a free radical-cured film.
