Outdoor HAA-cured polyester resin is a polyester resin product that uses HAA (β-hydroxyalkylamide) as a curing agent, mainly used for outdoor coating needs. Compared with the TGIC curing agent, the HAA curing agent has lower toxicity and irritation, and can maintain good coating performance in outdoor environments. HAA curing agent has high reactivity and can rapidly cure at lower temperatures.

Two-component TGIC polyester resin is a polymer compound made from polyols and polyacids through polycondensation reaction, in which TGIC (triglycidyl isocyanurate) is used as a curing agent or crosslinking agent in conjunction with another component (usually the main body of polyester resin). It has desirable weather resistance, chemical corrosion resistance, heat resistance, and mechanical properties, and the coating formed after curing has high hardness, good gloss, and strong adhesion. It is mainly used in powder, coil, and automotive coatings, and other occasions requiring high weather resistance, high gloss, and desirable mechanical properties.

View MoreHow Does Jiangsu BESD Ensure the Quality and Performance of Its Polyester Resins for Powder Coatings?
Since its establishment in 1998, Jiangsu BESD New Materials Co., Ltd has been committed to the production of polyester resins for powder coatings. Through continuous innovation and technological upgrading, it has become a enterprise in this field. To maintain a position in the highly competitive market, the quality and performance of products are crucial factors. BESD ensures that the quality and performance of its polyester resin products meet the high standards of the industry through a series of strict measures and management systems.
Technological innovation, laying the foundation for quality
One of BESD's important measures to ensure the quality of polyester resins is technological innovation. The company has an experienced and creative R&D team that continuously optimizes product formulas and improves production processes. By introducing the world's advanced equipment and technology, BESD is able to ensure the performance of its polyester resin products in terms of durability, adhesion, chemical resistance and mechanical properties.
In addition, the company is also committed to meeting the specific needs of customers and providing customized polyester resin solutions. For example, different industries have different performance requirements for powder coatings. The construction industry pays more attention to weather resistance, the home appliance industry emphasizes appearance gloss and wear resistance, and the automotive industry has high requirements for corrosion resistance. Through a deep understanding of customer needs, BESD is able to produce polyester resin products suitable for various application scenarios, ensuring that its products can adapt to different market needs and meet customers' special requirements.
Strict quality management system
Another key factor in ensuring product quality is a strict quality management system. BESD has passed the ISO:9001 quality management system certification, which means that the company manages every link of product design, production, inspection and delivery in accordance with international standards. Through standardized processes, the company can ensure the quality consistency of each batch of polyester resin products, thereby avoiding the problem of quality differences between batches.
In the specific quality management process, BESD starts with the procurement of raw materials and checks every level to ensure that all raw materials meet high quality standards. During the production process, the company uses advanced automated production lines to reduce errors caused by manual intervention and further improve the stability and consistency of the products. Before leaving the factory, each batch of products will undergo strict physical and chemical performance testing to ensure that it meets customer requirements and industry standards.
Advanced production technology and equipment
Advanced production technology and equipment are another important factor for BESD to ensure product quality and performance. The company has modern automated production lines in Yangzhou Chemical Industry Park, which not only improve production efficiency, but also enable precise control of the production process. Automated equipment can ensure that each production step is carried out according to predetermined parameters, thus avoiding quality fluctuations that may be caused by manual operation.
Environmental management and sustainable development
In addition to quality management, BESD also pays attention to the environmental management system and has passed the ISO:14001 environmental management system certification. The company strictly controls the emission of pollutants that may be generated during the production process and adopts environmentally friendly processes to ensure that the impact of the production process on the environment is minimized. As a manufacturer of polyester resins for powder coatings, BESD's products themselves do not contain solvents, have extremely low VOC emissions, and meet environmental protection requirements.
Perfect after-sales service system
In addition to maintaining high standards in product production and quality management, BESD's after-sales service system is also an important part of ensuring product quality and performance. The company pays attention to communication with customers, understands the problems encountered by customers during product use, and provides timely and effective technical support. Through close contact with customers, BESD is able to obtain market feedback in a timely manner, thereby improving and optimizing products according to actual needs.
