The development space of polythiol curing agent industry continues to expand. Yifeng New Materials is a leading enterprise in my country.

Polythiol curing agent is a room temperature or low temperature rapid curing agent that can be used in low temperature and humid environments. Polythiol curing agent appears as a colorless and transparent liquid with no special odor. Compared with other curing agents, it has the characteristics of good waterproofing, high strength, good durability, easy processing, and chemical resistance. It is widely used in casting and wood processing. , automobile manufacturing, ceramics, glass, cosmetics, electronic and electrical, optical materials and other fields have many applications.

The upstream of the polythiol curing agent industry chain supplies raw materials, including epoxy resin, β-mercaptopropionic acid, pentaerythritol, p-toluenesulfonic acid, thioglycolic acid, etc. Pentaerythritol is a polyol organic compound and is widely used in the production process of polythiol curing agents. my country’s annual production capacity of pentaerythritol reaches nearly 500,000 tons, making it one of the world’s major producers. In recent years, due to the continuous deepening of the country’s supply-side structural reform and the tightening of environmental protection policies, my country’s backward production capacity of pentaerythritol has been gradually eliminated, and the market penetration rate of high-quality, green and environmentally friendly pentaerythritol has continued to increase, which has provided a good foundation for the polythiol curing agent industry. Provide favorable conditions for development.

The midstream of the polythiol curing agent industry chain is product manufacturing, including tetramercapto polythiol curing agent, trimercapto polythiol curing agent, and dimercapto polythiol curing agent. Trimercapto polythiol curing agent is a low-temperature rapid curing agent and is widely used in UV optical glue, electronic glue, adhesives and other products. In 2022, global sales of trimercapto polythiol curing agents will reach nearly 15,000 tons, accounting for nearly 70% of the total sales of polythiol curing agents.

The downstream of the polythiol curing agent industry chain is in application areas, including foundry, wood processing, automobile manufacturing, ceramics, glass, cosmetics, electronic and electrical, optical materials, etc. Polymercaptan curing agents are environmentally friendly materials. Benefiting from the growth in downstream demand, their industry development space continues to expand. According to the “2023-2028 China Polythiol Curing Agent Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center It shows that the global polythiol curing agent market size will reach US$390 million in 2022, a year-on-year increase of 4.1%.

The major global manufacturers of polythiol curing agents include Showa Denko, TORAY, Huntsman, etc. my country’s polythiol curing agent industry has a high degree of concentration. Yifeng New Materials is the largest polythiol curing agent supplier in my country. Its independently developed polythiol 309, polythiol 405 and other products are widely used in the fields of photovoltaics, electronics and medical care. obtain widespread application.

Industry analysts said that polythiol curing agents are widely used and the industry is developing well. In recent years, driven by national policies, my country’s polythiol curing agent industry has gradually developed in a green and environmentally friendly direction. In terms of market competition, my country’s polythiol curing agent industry is highly concentrated, and Yifeng New Materials, as the leading company, occupies a large share of the Chinese market.
