Photoinitiators are essential components in the production of UV-cured coatings, adhesives, and inks. They undergo photochemical reactions when exposed to UV light, leading to the initiation of polymerization, crosslinking, or curing. As the demand for UV-curable products continues to grow in industries such as automotive, electronics, packaging, and printing, the need for high-performance photoinitiators becomes more critical. One such photoinitiator is 2-Isopropylthioxanthone (ITX), produced by Ningbo Inno Pharmchem Co., Ltd, a leading manufacturer and supplier of specialty chemicals.

ITX, also known as 2-Isopropyl-thioxanthen-9-one or 2-(1-Methylethyl)-9H-thioxanthen-9-one, is a yellow crystalline powder with a molecular weight of 254.36 g/mol. It has a melting point of 90-93°C and a boiling point of 372°C. ITX is highly soluble in organic solvents such as acetone, ethyl acetate, and toluene. It has a strong absorption peak at 366 nm and is activated by UV light in the range of 320-400 nm.

ITX is a versatile photoinitiator that can be used in various applications such as coatings, inks, adhesives, and sealants. It is compatible with a wide range of monomers and oligomers, including acrylates, methacrylates, vinyl ethers, and epoxies. ITX has several advantages over other photoinitiators, such as low odor, low migration, and high reactivity. It also exhibits good photobleaching and thermal stability, which ensures consistent curing performance over time.

ITX is particularly suitable for applications that require fast curing and high surface hardness. It can be used in combination with other photoinitiators to achieve specific curing profiles, such as depth curing or surface curing. ITX is also ideal for formulations that need to be cured under low-intensity UV light, such as those used in the production of flexible packaging and labels.

One of the key benefits of ITX is its low toxicity and excellent safety profile. It has been approved by regulatory agencies such as the US Food and Drug Administration (FDA) and the European Union (EU) for use in food packaging and medical applications. ITX has also been awarded the 'Green Label' certification by the China Environmental Labeling Program for its environmental friendliness and sustainability.

Ningbo Inno Pharmchem Co., Ltd is a leading manufacturer and supplier of ITX, with a production capacity of 500 metric tons per year. The company has a state-of-the-art manufacturing plant that adheres to strict quality control standards and uses advanced technology to produce high-purity ITX. The company's ITX products have been widely used in various industries in China and exported to countries such as the US, Europe, and Japan.

Ningbo Inno Pharmchem Co., Ltd is committed to providing customers with high-quality products and excellent service. The company's ITX products come in different grades and packaging options to meet the specific needs of customers. The company also offers technical support and customized solutions to help customers optimize their formulations and achieve the desired curing performance.

In conclusion, ITX is a promising photoinitiator with excellent properties and versatile applications. Its low toxicity, high reactivity, and compatibility with various monomers and oligomers make it an ideal choice for UV-curable coatings, inks, adhesives, and sealants. Ningbo Inno Pharmchem Co., Ltd is a leading manufacturer and supplier of ITX, with a proven track record of quality and reliability. Customers looking for high-performance photoinitiators should explore the market potential of ITX and the products offered by Ningbo Inno Pharmchem Co., Ltd.
