Optical Material

As photoinitiator, it is mainly used for silk screen printing ink, lithographic printing ink, flexo printing ink and wood coating. TPO can be completely cured on the pigmented surface of white or high titanium dioxide. It is widely used in various coatings. Because of its excellent absorption performance, it is especially suitable for silk screen printing ink, lithography, flexographic ink and wood coating. The coating does not turn yellow, the post polymerization effect is low and there is no residue. It can also be used for transparent coating, especially for products with low odor requirements. When used alone in unsaturated polyester containing styrene system, it has high initiation efficiency. Acrylate systems, especially colored systems, usually need to be combined with amine or acrylamide and other photoinitiators to achieve complete curing of the system, especially for low yellowing, white systems and thick films. When the photoinitiator TPO is used with mob240 or cbp393, the curing efficiency can be improved. It is the best extraction solvent for petroleum aromatics units and is also used as formylation reagent in fine chemical industry.

Liquid ammonia stabilizer used in refrigeration equipment, rocket propellant, oxidant for pyrotechnics, glass etchant, antistatic agent, molten salt component in metallurgical industry, etc

2-nitroaniline is mainly used as dye intermediate and synthetic photo panning agent, as well as the determination of iodide and production of pesticide carbendazim. The toxicity is greater than aniline. It can be absorbed by skin and respiratory tract, which is a strong methemoglobin forming agent. The high-iron hemoglobin can cause tissue hypoxia and cyanosis, which may cause damage to central nervous system, cardiovascular system and other organs.

2,4,6-trimethylbenzoyl phenyl phosphonate ethyl ester (photoinitiator tpo-l) is a liquid photoinitiator, which is used in the formulation system with low yellowing and low odor. It is commonly used in the fields of silk screen printing ink, lithographic printing ink, flexo printing ink, photoresist, gloss coating paint, printing plate and so on.

Lithium phosphate is mainly used in the production of color phosphor, special glass, optical disc materials, etc
