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.

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.

TR-BP is a high effective photoinitiator used in coating and printing ink. TR-BP can be used in UV Pigmented coatings for wood, metal and plastics, powder coatings, intermediate of organic pigment, medicine, perfume and insecticide.
