2-isopropylthioxanthone D3

2-isopropylthioxanthone D3 is a highly efficient photoinitiator that is widely used in the printing and coating industries. It is a yellow crystalline powder that is soluble in many organic solvents, such as ethyl acetate, toluene, and methanol. This photoinitiator is typically used in conjunction with other photoinitiators to promote curing in UV-curable inks and coatings. The chemical structure of 2-isopropylthioxanthone D3 consists of a thioxanthone molecule with an isopropyl group attached to the 2-position on the aromatic ring. This modification increases the solubility of the photoinitiator, making it easier to handle and process in commercial applications. The D3 designation refers to the purity of the compound, indicating that it is 99.9% pure. When exposed to UV light, 2-isopropylthioxanthone D3 undergoes a photochemical reaction that generates free radicals. These radicals initiate a chain reaction that leads to the crosslinking and polymerization of the resin matrix in the ink or coating. This process results in a cured film with excellent mechanical and chemical resistance properties. In summary, 2-isopropylthioxanthone D3 is a highly effective photoinitiator that is widely used in the printing and coating industries. Its chemical structure and purity make it an ideal choice for UV-curable formulations, and its photochemical properties lead to high-quality cured films.
