The market size of outdoor polyester resin continues to grow, with many domestic manufacturers

Outdoor polyester resin refers to curing polyester resins such as TGIC (triglycidyl isocyanurate), HAA (β-hydroxyalkyl amide) or IPDI (blocked isocyanate) commonly used in the production of powder coatings. Application fields Including building materials, home appliances, construction machinery, automobiles, high-speed guardrails, etc., they need to have aging resistance, corrosion resistance and other properties; its use scenarios are mainly outdoor, so it is called outdoor polyester resin.

The research and development of China’s outdoor polyester resin industry began in the 1970s. It first focused on the introduction of foreign formulas, production technologies and equipment. Later, against the background of the booming development of China’s chemical industry, the domestic outdoor polyester resin industry has made great progress. progress, and a number of well-known companies such as Anhui Meijia and Wenzhou Libang were born. However, domestic outdoor polyester resins are dominated by small and medium-sized enterprises, and there is still a certain gap between the company’s products and well-known foreign companies in the fields of production technology and high-end products.

According to the released “China Outdoor Polyester Resin Industry Market In-depth Research and Development Prospects Forecast Report 2023-2028“, in 2020 Since the year, the domestic environmentally friendly coating industry, represented by outdoor polyester resin, has entered a period of rapid development with normal encouragement. In 2022, domestic powder coating production has reached 2.78 million tons. In recent years, it has maintained an average annual growth rate of more than 9%, and its proportion in the coatings industry has also increased year by year, and the market space has continued to expand.

In addition, in recent years, the domestic chemical industry has faced increasingly strict environmental protection policies, and the development of green industrialization has become the development trend of the chemical industry. The “Comprehensive Work Plan for Energy Saving and Emission Reduction during the 14th Five-Year Plan” issued by the State Council in December 2021 clearly requires that by 2025, the proportion of solvent-based industrial coatings used will be reduced by 20 percentage points. The outdoor polyester resin production process does not contain any organic solvents, and the powder coatings produced have no VOCs emissions. They are green and environmentally friendly coatings and are chemical products strongly supported and encouraged by the country.

Industry analysts said that the future development trend of powder coatings is green, environmentally friendly and safe. Compared with currently commonly used epoxy resin products, outdoor polyester resin has increasingly prominent advantages in terms of environmental protection, safety, and quality. It is expected that in the next few years, with the continued development of engineering machinery, furniture, automotive coatings, photovoltaics, wind power and other industries, the demand for outdoor polyester resins in various downstream fields will continue to grow. Outdoor polyester resins rely on their good With product properties such as super weather resistance, corrosion resistance, fast and low-temperature curing, the market has great development potential.
