Market Drivers:
With the rapid development of high-tech industries such as 5G, smart terminals, photovoltaics, and new energy vehicles, the demand for polythiol curing agents in the high-end material markets such as electronic packaging, optical adhesives, and quantum dot films continues to grow. Especially in the fields of UV optical adhesives, silicon rod cutting adhesives, and electronic packaging adhesives, polythiol curing agents have become key materials due to their fast curing, high refractive index, and excellent bonding properties. In addition, the expansion of the photovoltaic industry has put forward higher requirements for refined cutting technology, which has promoted the market expansion of polythiol products such as silicon rod cutting adhesives, bringing new growth opportunities.
As global environmental regulations become increasingly stringent, the market demand for low-toxic, odorless, and environmentally friendly curing agents has increased. Traditional amine curing agents are prone to produce irritating odors and harmful volatiles, while polythiol curing agents have low toxicity and low odor characteristics, and have begun to upgrade to odorless direction to cater to environmental protection trends. Some companies have launched bio-based or degradable polythiol curing agents, which meet the requirements of sustainable development and are particularly suitable for fields with high safety requirements such as medical and food contact materials, bringing long-term growth space for the industry.
Polythiol curing agents have broad application prospects in high-performance materials such as aerospace, military, wind power, and rail transit due to their low-temperature rapid curing, toughening, and good weather resistance. For example, in new energy battery packaging, composite material manufacturing, and high-performance coatings, the flexible sulfur segments of polythiol help improve the impact resistance and ductility of materials. At the same time, with the widespread application of polymer materials in precision manufacturing, polythiol curing agents are expected to gain a larger market share in the fields of bonding, high-transparency resins, and become an important driving force for the new materials industry.

Restraint:
Although polythiol curing agents have unique advantages in fast curing and low-temperature curing, there are still amines, phenols, photocurable resins and other curing agents on the market as potential substitutes. Especially in the fields of high-end electronics and optical adhesives, new photocuring, nano-enhanced composite curing agents and other technologies are constantly upgrading, which may gradually erode the market share of polythiol. In addition, with the tightening of environmental protection regulations, the development of some sulfur-free and odorless curing agents may also pose competitive pressure on polythiol curing agents, forcing companies to accelerate product optimization and odorless improvements.

Opportunity:
With the increasing demand for efficient curing, polythiol curing agents are moving towards low-temperature curing, rapid curing and toughening. Compared with traditional polyamine curing agents, polythiol can be quickly cured at around -10°C, giving it unique advantages in low-temperature construction, winter repairs and emergency repairs. In addition, polythiol contains flexible sulfur segments, which can effectively improve the toughness of epoxy systems and enhance the impact resistance of materials. It is widely used in high-end fields such as electronic packaging, industrial coatings and aerospace composite materials.
With the rapid development of electronic manufacturing, optical materials and new energy industries, polythiol curing agents are moving towards high-end and multifunctional directions. For example, in the photovoltaic industry, polythiol is used in silicon rod cutting glue to improve cutting accuracy, reduce edge collapse and cracks, and improve component yield; in the optical field, high refractive index polythiol helps upgrade high-end materials such as quantum dot films and UV optical glue; in the field of new energy vehicles, polythiol curing agents play an important role in applications such as power battery packaging and thermal conductive glue, promoting technological innovation in the entire industry.
