TR-NPI-20400 is a high-performance, non-toxic photoinitiator known for its excellent deep curing capabilities and low odor. It's suitable for various applications, often replacing TR-907, and works exceptionally well in colored curing processes, especially when paired with thioxanthone.

TR-4-PBZ is a type II photoinitiator. It can be used as a photoinitiator in UV curable coatings and inks.

TR-DETX is a very effective type II photoinitiator, suitable for photopolymerization of unsaturated resins in combination with tertiary amine compounds. TR-DETX is used in coatings, inks, adhesives and circuit board printing.

TR-BENZOIN is a kind of photoinitiator for coatings, and can also be used for defoaming of powder coatings and synthesis of pharmaceutical intermediates. TR-BENZOIN can be used in UV pigmented coatings for wood, metal and plastics, powder coatings, intermediate of organic pigment, medicine, perfume and insecticide.

TR-NPI-601 is a highly efficient photoinitiator that provides excellent curing and anti-yellowing properties. Initiated radical polymerization of some unsaturated resins under UV and near-visible light irradiation. TR-NPI-601 has been tested and proved to be suitable for UV curing varnish and paint system, such as wood, paper, metal, plastic, optical fiber, printing ink and prepreg system. In opaque white and tinted furniture paints, very low levels of TR-NPI-601 provide excellent cure and anti-yellowing properties. And the excellent absorption properties of TR-NPI-601 make it also suitable for deep curing.

TR 4 MBP is a general free radical photoinitiator with high initiating activity, which is widely used in wood coatings and inks.

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-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-BDK is used in UV-curable resins with good effect , It has strong absorption performance in inks, varnishes and other systems. TR-BDK is widely used in coating, inks, photo resists.

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.
