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-184 is a white crystal powder act as a high-efficiency non-yellowing photo-initiator, which can be used in light-curing varnish system. It can be applied in platics and metallic finish varnishes as well as a an excellent starting aid for UV-printing inks.

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.

TR-TPO is an efficient curing agent, especially suitable for long-wavelength LED light curing of unsaturated resins. TR-TPO can be used for coatings on wood, metal, plastic, paper and optical fibers, as well as UV-curable formulations for printing inks and adhesives.
