Crowned in Glory · Embracing a New Era | Zhengjie Group's 2025 Wuhan Powder Coatings Exhibition Concludes with Great Success

  As the wave of innovation in green coating slowly subsided in the river city of Wuhan, a grand event that integrated technology exhibition, academic exchange, and industry recognition provided a vivid footnote for the development of the polyester resin industry. On November 3-4, 2025, the two-day Wuhan Powder Coating and Coating Industry Exhibition came to a successful conclusion. Zhengjie Group not only made a splendid appearance with its new polyester products but also achieved triple honors: ranking fourth in the polyester resin industry, third in the HAA curing agent industry, and winning the second prize for industry papers. With its professional strength, Zhengjie Group presented an impressive "answer sheet" at this industry feast.

  The recognition of technical prowess is evident not only in market sales feedback but also in breakthroughs in academic fields. At the industry annual conference forum held concurrently, the paper titled "Structural and Performance Characterization of Ultra-pure Crystalline Hydroxyalkyl Amide Curing Agent" submitted by the company stood out from numerous entries and won the second prize for outstanding papers, thanks to its precise addressing of industry technical pain points and innovative research perspective. The paper comprehensively introduces the physicochemical technology and application performance indicators of the "Ultra-pure Crystalline Hydroxyalkyl Amide Curing Agent" developed by Zhengjie Group. It deeply analyzes the quantitative relationship between HAA purity, impurity content, and yellowing resistance, focusing on the development path of "self-developed standard substances/testing methods - high-level enterprise standards - standardization team building" for the transformation and upgrading of the manufacturing industry. It fully demonstrates Zhengjie Group's profound research and development accumulation and high-quality development strength in the field of powder coatings. At the exhibition site, the research and development team conducted special exchanges and sharing centered around the paper's achievements, sparking widespread attention and heated discussion from participating experts and peers.

  Looking back on the exciting two-day exhibition, the Zhengjie Group's booth was always buzzing with excitement. The three major new product achievements became the focus of everyone's attention, demonstrating the strong potential for innovation in polyester resin:
  (1) Low-temperature curing resin
  ZJ3566: HAA curing system polyester resin, with a curing ratio of 95/5 with HAA, and a curing temperature of 160 degrees for 10 minutes, has good leveling performance, mechanical properties, and weather resistance. It has good anti-frosting effect and reduces energy consumption by 20%. It impresses customers in the fields of home appliances, home decoration, and automotive interiors, and many companies expressed their intention to cooperate for small-batch trials on the spot.
  (2) Flexible polyester resin
  ZJ9003/ZJ9012: Two-component matting polyester resin with a gloss of 20-30%, boasting excellent flexibility and weather resistance. It is suitable for color-coated plates and powder coatings demanding flexibility, offering a new approach for rapid curing of coil materials such as steel coils and aluminum coils for mass customers.
  (3) Polyurethane resin
  ZJ8300: With high hardness, excellent leveling properties, and chemical resistance, it is formulated with a curing ratio of 83/17 with curing agent B1530. It is suitable for powder coatings such as flat and textured coatings, providing a practical raw material solution for many coating companies seeking environmental transformation.

  During the exhibition, the "Professional Service Team" composed of the marketing team, R&D team, and application service engineers from Zhengjie Group received more than 200 groups of visiting customers and conducted over 100 one-on-one technical consultations. From the weather resistance and protection of automotive parts, to the exquisite texture of home appliance casings, and to the durability of building profiles, each batch of products carries the trust of customers. Many customers expressed that through on-site observation of product performance and in-depth exchanges with the technical team, they not only gained a clearer understanding of the technological trends of polyester resins but also witnessed the professional strength of Zhengjie Group in R&D and service. They looked forward to establishing long-term and stable cooperative relationships in the future.
